Tablet PCs in the Sun. One Winner.


The sun is shining so it’s time to take a bunch of Windows 8.1 tablets and do some sunlight readability testing. This is an operation where I lay all the tablets in the sun, choose the best one, make a cup of tea and enjoy some reading and Vitamin-D intake. It’s a tough test.

Ultrabook Ecosystem Technology Requirements – IDF 2011


ultrabook-ecosystem

There’s much more to Ultrabooks than “Thin, Responsive and Secure.” In terms of laptop design the Ultrabook is one of the biggest overhauls ever. At IDF last week I learnt just how complex the Ultrabook design is and why Intel is calling-out to the ecosystem to help create the best Ultrabook components and designs.

Screen Size Analysis (Sub 12″) Feb 2011


This is the sixth report on sizing trends in PCs below 12 inch screen size (and above 5 inch) appearing in the German market through the popular price comparison engine, Geizhals.at (*1)  The last one was done in August 2010 In this report you’ll see  a big jump in overall numbers, a reversing of the decline in 7 inch devices and a turnaround in the 10 inch segment.

Screen size distribution

The big jump in numbers is clear to see from the top graph. Total numbers jumped by 83 and this is likely to be due to the Christmas season and introduction of new model ranges following IFA 2010. Surprisingly, the 10 inch segment has grown in numbers and %. A lot of this is attributable to dual-core Atom N550 devices.

  • Over 20 Intel Atom N550 devices appeared exclusively in the 10 inch category.
  • 62% of the devices are running on Intel Atom. One year ago, this figure was 78%  Remember that the segment includes some devices running laptop-grade CPUs and there’s an influx of AMD and ARM devices in the top and bottom end of the 5-11 inch range.  This is not just an analysis of ‘netbooks.’
  • The 7% segment had the biggest percentage growth (over 300%, from a very low starting point) and the 10% segment had the biggest numeric growth (63)
  • Including Android, over 14% of the segment runs a Linux kernel. One year ago this figure was 5%.  Almost all of this growth is within the ‘tablet’ style of devices.
  • Only 13% of the devices weigh 1KG or less. (up from 10% one year ago – again, growth is in the tablet segment)
  • 18 devices now include Nvidia ION2.  All of these are from a single manufacturer – ASUS.
  • Total number of tablet form-factor devices – 60 (not including 4.8 inch) which is about 10% of the total sub 12% screen size market.

The cheapest devices (based on lowest price offered) are:

  • X86/Windows Laptop – Samsung N145 at 228 Euro
  • ARM Tablet – Nexoc Pad 7 (Android 1.5) at 99 Euro
  • X86/Windows Tablet – Archos 9 at 402 Euros.

Also of note is the larger spread of GPU technologies, the increased us of SSDs (even in the X86/Windows segments) and a large number of dual-core CPUs. Dual core CPUs make up a 30% of the 10-11.6 inch bracket now.

In the last report I talked about a netbook freeze.  Certainly the trends for search and news seem to be heading south (see below for ‘netbook’ trend)  but the increase in numbers of 10 inch devices indicates that there is still interest from manufacturers. The increase in SKU’s, however, could be misleading as we’re seeing an increase in the number of colour options, CPU options, GPU options and screen options that use the same chassis. Acer and ASUS each have over 90 different model types in the German market in the 10-11.6 inch category.

I think most people in the netbook field would agree we’re seeing a levelling of interest and manufacturers are using offers and personalisation to attract sales in this mainstream part of the segment lifecycle.

For mobility fans though the message is clear. There are more options than ever and competition is increasing which will drive improvements in software and hardware very quickly. Certainly we will see the tablet segment grow and it will be interesting to see how the 5-9 inch segments move when we do the next analysis in about 3 months time.

Warning: Please remember that this is a single data-source analysis of what is happenning today, in the German market. This is not a complete market analysis report. You may use the data and images but please also reference this article which includes this warning.

*1 Based on SKUs, not model families. Note that Geizhals have now moved all tablets to a new category called ‘tablets.’ This category was included in the analysis. An English language (and UK market) version of Geizhals is available at Skinflint.

Pixel Qi Screen Upgrade Available To All


I’ve long been a fan of the Pixel Qi screen technology, its ability to work in direct sunlight is something us tech folk have been waiting on for a long time. At Computex 2010 Pixel Qi showed us the technology compared with a Apple iPad and the results are stunning. JKK also got some time with the people at Pixel Qi to show us more how the technology works and the difference it makes to outdoor visibility.

MKPQ01-2T

Well we no-longer have to dream of working outdoors in the sun as MakerShed are selling the Pixel Qi 3Qi 10.1 inch upgrade kit. For a cool $275.00 and a little time you can upgrade your own netbook;

MAKE and Pixel Qi announce the availability of a revolutionary LCD display technology from Pixel Qi–the 3Qi display. This one-of-a-kind, plug-and-play 10.1-inch display offers two modes–an easy-to-read, real colour, multi-media mode or a crisp, low power e-reader mode. The sunlight-ready, e-reader mode makes it easy to use outdoors.
These screens rival the best e-paper displays on the market today but in addition have video refresh and fully saturated colour. The e-paper mode has 3 times the resolution of the fully saturated colour mode allowing for a high resolution reading experience without sacrifice to super colour fidelity for graphics. In addition these screens can be used in sunlight.

Currently the only tested models are the Samsung N130 & Lenovo S10-2 but they state that it should be compatible with other 10.1 inch netbooks and are testing more models as we speak.

This is obviously going to be a popular kit and MakerShed are already out of stock. Pre-orders are live for the next batch.

Xperia X10. Is Total Convergence The Answer?


When the N900 was launched, Nokia positioned it as a total convergence device. It’s a dream (and the subject of my first ever blog post in 2006). The X10 is also aiming to be a total convergence device and does an incredible amount of activities with impressive quality but again I say no; and that’s not all. Battery life is a major problem with every smartphone I’ve ever used. I wrote about the problem back in 2008 and again in January. The X10 re-confirms my theory. There is NO SUCH THING AS IDLE and screens and communications continue to take the lions share of battery drain. Smartphones, when used professionally  as smartphones, don’t bring all-day battery life.

X10compare

Forget talk about cpu idle power claims because it’s totally irrelevant. 2W is the headroom needed to do all the things the marketing people tell you are possible and assuming you ‘only’ use the device for 15 minutes every hour, you’ll need a 7.5wh battery to get you through a full day.

The X10 has a 5.5wh battery which means it’s not going to hit the mark for many. It needs attention, a top-up late in the day and if you’re to be ready for the next day it needs plugging in before you go to bed. That late-day top-up is a big risk if you’re a pro user and relying on being able to take an important phone call or respond to an email at any time and if that risk is there, you’ll need to manage it. In this case it means either a spare battery, a universal charger or, and I suspect that this is going to be the easiest route for many, take a second phone. Either way, you’ve got a second device and a problem.

Corner cutting.

The X10 pushes the boundaries in so many ways but it does it within the confines of a pocketable size, smartphone pricing and smartphone life-cycles and that means (and always will mean) cutting corners. The web experience is great but even though you’ve got 800×480 pixels, the pixels are too small. a 5 inch screen has always been better for mobile web browsing from the hand and now that people are experiencing even bigger handheld web experiences, the 4 inch screen has issues. Zooming to click a link is a pain in the backside.

Then there’s the camera. How do you keep the price down and still provide a superb photo solution? You stick to daylight-only scenarios, drop the flash and choose a daylight sensor. The X10 is crap at low-light and flash situations. My 2 year-old N82 beats the pants off it.

How do you keep the design simple, reduce parts costs and avoid having to ship 500 different physical keyboard layouts? You make a tablet device with a software keyboard. Losing 50% of a landscape screen to a keyboard isn’t nice but it’s a great way to reduce the time-to-market costs.

How do you tackle the audio issues? Speakers need space, always. To fix that problem you ship it with a standard 3.5mm headphone port and hope no-one wants to use it as a radio. The speaker on the X10 is far from ‘top quartile.’

A great MID.

A 500 Euro smartphone is an expensive item but when you look at what the X10 is giving you it’s hard to put much weight on the corner-cutting. In terms of mobile internet, the X10 blows away any Intel-based MID I’ve tried. Sure, I’ll have to put up with a no-flash experience but the X10 brings me email, PIM and calendar integration, sync and accessibility that I’ve never had before. The dedicated GMail J2ME app on my old Nokia 6280 was really fast but this is something else altogether. Being able to push information around (sharing with email, IM, Twitter, Flickr, Facebook and other important networks) is easier than on a PC and when you add the always-on feature, GPS (location based search adds a lot of value) a WVGA video capability and an 8MP camera that puts every PC-based 1.3mp webcam to shame, you’ve got something special that goes way beyond browsing. With 4-6hrs full-on web browsing time, 9GB storage and a 138gm (measured here) weight, you can forgive it not having the ability to beat a dedicated digital camera in a low-light photography test.

What have I learnt?

I’ve learnt that I use the Internet too much for a smartphone. Actually I knew that already which is why I’m still looking for the ultimate MID but the X10 serves to re-iterate that point. No smartphone battery can keep up with me.

I’ve learnt that Android fits me perfectly. I’m a Google user and Android brings my services to me in a way that no other device ever has and that means that I won’t pursue a Windows-based mobile internet device. Actually, I never did. I knew that a dedicated OS was needed from day 1 but the choice just hasn’t been there. [History: Carrypad was started in 2006 to journal my question for a mobile internet device]

I’ve learnt that I love having a top-end, stylish smartphone. Just because! (Who doesn’t?)

I’ve learnt that the ARM/Android platform is able to bring a consistently high-speed, multitasking and flexible web experience. I experienced it on the Archos 5 and it’s here again on the X10. Android will easily scale to bigger screens and given the apps, would be able to provide a productive internet experience.

I’ve reaffirmed that the Marketplace is critical. Without it, Android devices just can’t keep up.

I’ve learnt that the X10 may not be for me but I know it will be difficult to part with it. I’ve tasted Google Android at 1Ghz and I don’t want to step down from that. The Dell Mini may be my savior.

HTC Nexus One / Desire, Motorola Milestone / Droid

Many of you have been asking how the X10 compares to these two phones. I’m afraid I can’t comment on the Desire and N1 because my hands-on was with a device that kept crashing but from my brief hands-on with the Nexus One I can say that the experience is very comparable. As for the Droid, I’ll immediately say that the Droid is a better value device. It’s available for under 400 Euros now and has the 2.1 upgrade. It offers similar photo, web and UI experience. If you’re a Google user and smartphone oriented,you’re not going to walk away from a Droid purchase unhappy.

The fact is that all five devices are top quality Android smartphones and offer an experience that will is likely to lock you in to the Android way.

Detailed first impressions and review.

I’m writing about the X10 in detail on a separate sub-blog and have just posted Part 1 of my first impressions. The article highlights three potential show-stoppers so take a look, comment and check back soon for part 2 where I cover the good stuff. Part 2 is going to be much longer than Part 1 I’m sure!

Screen Size Analysis (Sub 12″) March 2010. ‘Hi-Res’ and Pinetrail Feature.


This is the forth report on key trends in PCs below 12 inch screen size appearing in the German market through the popular price comparison engine, Geizhals.at . (Based on SKUs, not model families.) The last one was done in November 2009

In this report you’ll see the big jump in numbers coming from the new Pinetrail devices. Below the graphs I highlight some key numbers.

total_number_of_sub_12__pcs_(germany)

Number of SKUs in the market.

sub_12__screen_size_distribution

The big jump in numbers is clear to see from the top graph. Total numbers jumped by 115 with Pinetrail making up a large portion of that number. A bigger trend I’m seeing is the introduction of 1366×768 displays. Nearly all of the 101 devices with hi-res screens have appeared in 2010.

Other ‘trends’ that are clear from the data provided in the comparison engine:

  • 78% of the devices are running on Intel Atom. Remember that the segment includes some devices running laptop-grade CPUs. This is not just an analysis of netbooks.
  • The percentage of devices in the 10% segment dropped but the number of devices still rose.
  • There were percentage increments in the 5 inch, 8 inch, 9 inch (ipad) segments. Previous reports showed decline in these segments.
  • Only 5% of the devices are offered with Linux.
  • There’s a 3:2 ratio of Glossy to Matt screens.
  • Only 10% of the devices weigh 1KG or less.
  • Very few Nvidia ION devices have reached the market. Only 3% include the ION option and all of these are ION V1. Devices with Pinetrail + ION are expected in the next snapshot so this number should increase.
  • The cheapest device (based on lowest price offered) is still the Hercules E-Cafe EC800 is more expensive now – 183 Euros (up from 151) but the cheapest Intel Atom netbook isn’t far behind at only 188 Euros. (lowest price.)

One thing I note every time I do this is that there are a lot of end-of-life PCs still being offered. For example, the EeePC 701 is still hanging around. It’s difficult to measure but it looks like up to 100 of the devices in the market are remnants.

When we look again in June I expect we’ll see a much smaller increase in numbers. The first ION2 devices will appear though and if the ‘tablets’ and MIDs start flowing into the market as promised, we should see growth, albeit very small,  in the sub 1KG and sub 10 inch segments with a corresponding increase in non-Windows numbers.

Mobile Computing Segmentation and Capabilities. (Updated from DevMob 2010)


Thanks to the great crowd at DevMob2010 in London last week, I’ve had some good feedback to my scenarios and segmentation diagram which was originally created in 2006 and is now updated and re-published under CC license. It should help as a stimulus for software developers thinking about the possibilities in the space between smartphones and netbooks and can help device designers to think about usage scenarios. Customers will also find it useful to pick out their own usage scenarios and to see what type of device fits with their requirements.

FEEDBACK IS ENCOURAGED. If you have thoughts, please add them to the comments section below.

During my session at DevMob I had a set of suggestions which I’ve added to the diagram. It was interesting to hear suggestions for the 8-10 segment which included Multi-touch/User gaming (many players, one device) and multi-person video viewing. Those are two models that the iPad is targeting very closely. We also added ‘Media Overview / Chooser’ to the 8-10 segment based on the need for screen space for an overview of images, album cover art or video’s.

Many thanks to all that took part in the sessions at DevMob and thanks to all of you that took the time to present and talk about your ideas in this space. I hope to see you all again at the next DevMob2010 and at other events in Europe.

The diagram (V2.0) is available here (PDF)

Notes are shared in a Google Document here.

Update: I’m experimenting with a slightly different layout based on feedback below.  The segments have been re-drawn to represent a more fluid crossover point.

V2.1 diagrams are here.

Pixel Qi Low-power / Daylight Screens go to Mass Production


pq_screen_outsidesm.213195607 While Intel, AMD, ARM and VIA might want you to believe that low-power silicon is the answer to all battery life problems, the truth is somewhat different. We’re at a point now where all silicon, be it X86 or RISC-based, can perform at low enough power consumption that other components on a device become more significant in the power, heat and battery life equation. Talk about ‘ídle’ power drain is irrelevant when you’re using a device in constantly-connected mobile computing scenarios.

Two of the main power problems are the wireless radios (chattery 3G transmissions being a huge problem) and the screen. Despite improvements in backlight technology, a small 3.5 inch LCD screen still takes about 0.5 watt when fully backlit. A 10 inch netbook screen will take up to 3 watts. If you’re just reading text, that backlight is taking way over 50% of the total battery drain and as we move to lower-power silicon platforms, the percentage rises higher.  This is a particular problem for mobile users as we tend to moving about in different lighting situations and tend to pump the backlight up higher than desk-bound users.

One of the solutions that many have been watching closely for the last year is the technology developed by Pixel Qi. The trick they use is rather simple. They reflect ambient light back through the LCD matrix to reduce the need for backlight. This works indoors and out. The implementation more complex than that of course but the result is that in bright ambient light situations, you will see a big reduction in backlight power drain. The contrast and pixel density is also said to produce e-ink style results too so it could help to make screens more comfortable to read. Pixel Qi have even kept the process fairly cheap to implement by using existing technologies. Win win win!

Screens up to 10 inchare going into mass production right now and we should see the first devices before the end of the year. Expect products to reach customers in 3-6 months based on the time it usually takes new products to reach the market. As for prices, I’m guessing the marketing teams will use this to throw another $50 on a standard netbook price for a ‘sunlight readable’ version but overall, you should see about 10-20% improvement in battery life on a standard netbook. As we move forward with lower power platforms and radios, the advantage goes up and I see this sort of technology becoming the norm rather than something that is offered as a premium upgrade.

I’m looking forward to testing out a nice thin 7 inch ultra mobile PC with this tech. Not that I need to read for 7-10 hours between charges but keeping that battery over 50% full always gives one a better feeling when mobile.

4.3” is not too large for a Smartphone (say WM and UMPC fans.)


A few months ago I took hold of the 4.1 inch Toshiba TG01 and said no! It’s too big for my pocket.

It’s the size that really struck me. For a phone, it’s HUGE! There’s simply no way that the average person is going to be able to use this as a 24/7 phone. I don’t mean to imply that the TG01 is meant to be a 24/7 phone but it proves that convergence between the full internet minimum screen resolution of 800×480 and the 24/7 total convergent device is simply not going to happen for most people.

Yesterday, following news on the HTC Leo, a Snapdragon powered 4.3 inch slate phone that we covered a while back, WMPoweruser asks the same question.

It seems that most of you readers really are happy with big screen devices.

43inch-1
52% of UMPCPortal readers voted ‘No’ 4.3 inch is not too big for a pocketable phone.

43inch-2
64% of WMPowerUser readers voted ‘No’ 4.3 inch is not too large on the HTC Leo.

This drive for convergence doesn’t bring me any closer to my ideal 3-device strategy but I’m happy to accept that there are a ton of people out there that want ONE device to cover phone, MID, navigation, camera and a certain amount of productivity tasks. All I can say is that that the voting numbers probably represent a niche of high-end gadget and mobility users and that I fit into a class of people that doesn’t wear cargo pants!

On a serious note though, I find this drive for convergence a bit cheap from a marketing perspective. I think the long-term practicalities of converged devices are limited, that quality suffers due to physical constraints and that eventually, people end up buying dedicated tools for their tasks anyway. The marketing people just want you to THINK that it can do everything. Don’t they?

I’m guessing we’ll have a good discussion about this below and that someone will say – ‘the best camera/pnd/pmp/umpc/mid is the one you have with you.’ You have a good point. I’m off to have another sleepless night over the matter.

Screen Size Analysis. September 2009.


Back in May, I took a look at the small notebook PC market to try and determine the distribution of screen sizes. I took screen sizes of 11 inch and under and plotted them on a graph to find the unsurprising result that the 10 inch screen size was the most popular and the original 7 inch netbook had all but died. In May 2009, 68% of the devices had a screen that was over 10 inch. I also promised to revisit the subject. By taking a second snapshot today, I’m able to work out what sizes are growing and waning in popularity. It’s only a second data point but it’s very interesting.

There has been a huge growth in the 11 inch segment (and 12 inch but that’s out of scope for this mobile-computing-focused data set) which means that of all the SKUs, 79.6% are now 10 inch and over.

sub_12__screen_size_distribution

  • 79% of devices have screens of 10 inch and over. (was 68%)
  • The 11 inch segment grew by 65%
  • The 5, 6, 7 and 8 inch segments all declined in % (and absolute number of devices available)
  • The 8 inch segment declined by over 40% from 61 devices down to 45
  • Linux-based devices still count for 8.5% of the devices (no change)
  • 80% are over 1KG (12% increase)
  • Nearly all netbooks under 1KG are 1st-gen devices that are outgoing.
  • T91blackThe sample size is 279 (up from 243)
  • The cheapest device in the segment is the Hercules eCafe EC-800 based on the AMD Geode CPU. 160 Euros. Hercules also make the cheapest Atom-based device, the EC-900, for 190 Euros.

In general it’s a sad story for mobile computing fans especially as some of the best ultra-mobile solutions aren’t even reaching the normal online channels but there’s one shining star in amongst that lot. The ASUS EeePC T91 for 450 Euros, in Black, with a 24-month guarantee. 960gm, 5hrs battery life and a whole lot of flexibility!

As before, the results are based on data from the German/Austrian price comparison engine – Geizhals.at and include all notebooks (and almost insignificant numbers of tablets and UMPCs) with screen sizes equal-to or below 11 inch. Again, I’ve put a note in my calendar to review the situation in 3-4 months time.

Pixel Qi shows off new power saving screens [video]


pixel qi screens We’ve been hearing rumblings of this for a while now, but it seems that Pixel Qi is now showing its new dual mode power saving screens. Based on the screen featured in the OLPC project’s XO computer. Essentially Pixel Qi has designed an LCD screen which can display just like you would expect a standard screen to do, but it can also toggle to  an E-Ink like mode which uses ambient light to display the on screen image rather than a backlight.

What are the implications for the mobile device user? The screen is one of the single largest power consuming components of modern mobile devices. The ability to turn off the backlight and still be able to see the screen from ambient light would mean large power savings. With the XO laptop, the screen was actually able to stay active while the motherboard turned off. However, modern netbooks are running much different operating systems and hardware than the XO, and aren’t yet designed to be able to accomplish that extra power saving step. The dual mode means that you can still have a full color display at the flip of a switch, then go to the power saving backlight off mode which reads great in direct sunlight and also saves battery life. If Pixel Qi can keep these screens to a reasonable price, I think we’ll see them popping up on netbooks once they hit full production, but the power saving isn’t going to be mind-blowing.

A few things garnered from the following video. You’ll notice that they are demoing the first batch of their screens on what appears to be an Acer Aspire One D150 [Portal page]. It is mentioned that they are stock Acer’s bought online, then modified to work with the new screen. It doesn’t sound like this technology will be coming to our favorite touchscreen devices any time soon as the particulars of touchscreen technology don’t play nice with the visual quality of the Pixel Qi dual mode screen.

If you’ve used a Kindle, you probably know that the refresh rate is rather abysmal compared to a computer screen that you might be used to. I was impressed to see that the transreflective (E-Ink like) mode of the Pixel Qi screen actually retains a rather good refresh rate meaning that you can work just like you would normally even with that mode enabled (they even show a video being played). If it were E-Ink, you would need to toggle out of the mode just to see the mouse move at a reasonable rate.

Take a look a the video below to see the Pixel Qi screen in action:
