Marmot iTouch Multi gloves mini-review and video demo

Tags: , , , , , ,

I’ve been on vacation for the last week doing some snowboarding in Colorado, but it wasn’t all play. I’ve been doing an accessory review for you, our good readers. For the last week, I’ve been testing the Marmot iTouch Multi gloves for use with capacitive touchscreens.

What Are They?

3

The iTouch Multi gloves from Marmot are gloves that have a special tip on the index-finger and thumb that allow one to use capacitive touch devices that normally only work with bare fingers. I bought mine at a local ski/snowboard shop for only $35. These gloves aren’t thick (or water-resistant) enough for use as dedicated skiing/snowboarding gloves, but they work great as liners for larger gloves or for stand-alone gloves in brisk weather.

How do they work?

On both gloves are pads on the index-finger and thumb that have a special material that activate the capacitive touch device. The material helps transfer the field that you fingers’ naturally generate which acts to disrupt a field created by a capacitive touchscreen, thus locating the region that the screen has been touched. It seems that these gloves are rather new, as I can’t even locate them on Marmot’s site, so I unfortunately don’t know the exact origin of the material. The special material is flexible, and it goes over top of the regular glove material, so you thumb and index-finger stay just as warm as your other fingers.

How do they perform?

 

I’m pretty impressed with the gloves. They work about as well as I expected them to. I bought these gloves with the desire to be able to operate the basic functions of my iPhone 3G in the cold without having to remove my gloves. I also wanted them to function as a liner for larger gloves so that I could take my outer gloves off while snowboarding and be able to use my phone on the slopes without my hands freezing off.

The special material on the index-finger and thumb work well to initiate touchscreen input. Of course it isn’t the surface of your real finger, so it is hard to be as accurate as normal, but as long as you are careful, it is possible to touch right where you are trying to. Sometimes it is easiest to use the side of the glove tip where it comes to more of a point to hit exactly what you want. The gloves make it easy to answer and place phone calls without taking your gloves off. Though it might take more time, you can also respond to text messages. When returning texts, it is only practical to type with one finger; you won’t be typing with two thumbs like you might normally.

I only have two issues with these gloves. The first of which is grip. The gloves are covered on the palm side with little rubbery grips that look just like the red logo on the index-finger. While they probably assist your grip somewhat, holding the iPhone is still analogous to holding a wet bar of a soap. Ok that might be a bit of an overstatement, but I would recommend being very careful while holding your electronic device. For me, holding and typing with the same hand was totally out of the question. While I was on the ski lifts, I would hold my iPhone firmly with one hand and use the other to navigate, any other way would just be asking to lose your iPhone to the snow 30 feet under you. Stopping to answer a call on the slopes wasn’t much of an issue. All I had to do was take off my outer glove and slide the slider to answer. I was able to talk on the phone without completely taking off my gloves, which is very nice when you are out in the cold.

My second complaint is build quality. The gloves would probably hold up very well if they were used by themselves. However, a week of being used as liners is already taking its toll. The special pads are already frayed. After prolonged use as liners, it seems like they would degrade fairly quickly. As I said, during stand-alone use, they would probably last much longer.

Overall I’m pretty satisfied with the gloves, and I feel that they are priced fairly. Any glove makers out there think they have a better pair of capacitive touch enabled gloves? Contact me at Ben [at] umpcportal.com if you would like to have them reviewed.

3G iPhone proves that battery life is a problem for everyone!

This tickled me. A post on Friendfeed a short while ago…

“As the iPhone begins to resemble and be used like a computer, we will have to contend with challenges like crashing and battery life.” [Steve Rubel]

He’s right. Many people still assume that smartphones have excellent battery life compared to UMPCs. The reality is slightly less exciting if you use both devices for mobile Internet activities on a regular basis.

Apart from having a little giggle, the comment also reminded me to check up on the reported iPhone 3G battery life and compare it with my figures. I came up with an interesting article from AnandTech who have completed a browsing test which resulted in a dead iPhone in just over three hours. That’s much less than the 5-hrs quoted by Apple. It’s not even the most power-hungry test you could do on an iPhone. Try doing some Voip, live tracking or even IM with some music playing in the background and you’ll have a dead iPhone in under 2 hrs. Well, you would if the Iphone would let you run 3rd party background tasks!

3G radios, GPUs, displays are all going to take a lot of power whether they’re on a UMPC or a smartphone. Add 3rd-party software into the mix and you find that if you want the FIE on a regular basis, there’s no substitute for a fat battery!  As I mentioned in a previous article, 10wh is about your minimum battery size for any serious mobile Internet device in 2008 and 2009. The battery in the iPhone is only 5wh (possibly only 4wh according to this article.) 

In perspective, the iPhone 3G is still an impressively efficient device. 1.5W maximum power drain makes it one of the most energy efficient MIDs around and it’s still leading the way in the consumer-oriented market. In 2007 we were seeing best-of-breed UMPCs taking 9W to do similar 3G browsing tasks. Later in 2008, the differential will shrink to just 2 or 3watts and in 2010, the differential will be close to zero but in all cases, you still need that big battery if you need the FIE for long periods between charges. For now, the multi-device strategy still seems to be the best for you pro-mobile users.

[If you spot any other iPhone 3G battery life tests that were done under 'MID' conditions. Please drop me a comment. I'm interested. Thanks.]

Two of the Worlds most Energy Efficient Mobile Internet Devices launch on Friday.

Tags: , , , ,


iphone3gsmallEnergy efficiency is, without a doubt, the most important design factor for any pocketable Ultra Mobile device. On Friday this week, there are two very important launch events taking place that will highlight the advances made in energy efficient computing over the last year. The two devices will also show how us close Intel and ARM partners really are in the race to provide handheld, Internet-focused computers. MIDs.

On one side of the fence, in PC land, Sharp and Willcom will release a pocketable slider-keyboard mobility-focused device. The Sharp Willcom D4 will be running Windows Vista on the Intel Silverthorne/Poulsbo platform also known as Menlow and is likely to be one of the most energy-efficient 3G-enabled PC’s so far.

On the other side of the fence, in smartphone land, Apple will release a smaller, 3G-capable mobility-focused device running a highly optimised desktop operating system. The iPhone 3G will be running ARM-based processors and is likely to be one of the most energy-efficient 3G smartphones so far.

The Willcom D4 is said to have (independent tests) a 3G-active time (Internet activity) of around 1.5 hours and it runs a 7wh battery.

The iPhone 3G is said to have (Apple figures) a 3G-active time (Internet activity) of around 5 hours and it is likely to run (my estimates) a battery of about 5.5wh.

3G-active Internet time is a worst-case measure of device efficiency so, based on these early figures, it looks like the Menlow-based device will use about 4.5W and an iPhone will use about 1W.  More after the pic…

iPhone 3G plans revealed in Germany. (Updated)

Tags: , ,


iphone3g As expected, the iPhone is very expensive indeed. [See the update below. The source linked to the wrong PDF!] Prices do seem more reasonable now that we’ve got the correct info!

Not only that but the data plans are restricted right down to the point where on the entry-level plan, you get no data at all! How’s that for the phone that’s supposed to open up the world of the Internet to your pocket?

T-Mobile in Germany have released the pricing plan and small-print for the iPhone 3G which starts at 29 Euro per month for just 50 minutes of inclusive calls. No Internet included, oh wait, one of their Flyer pages mentions 100MB of data at EDGE speeds only!  Add the 249 170 Euro cost of the iPhone on top along with a 30 Euro connection charge and you’re not exactly getting the best smartphone deal on the block!

Update: A further check on the data reveals that Digital Living highlighted the wrong tariff. Joel spotted that the PDF was 3 months old. The NEW PDF shows a slightly better offer. If you order the iPhone before end of August you get 500MB of HSDPA included and 50 minutes of calls for 29 Euro. It’s still more expensive than most offers but considering the 8G version is only 170 Euro, it’s a reasonable deal.

For those not familiar with the pricing in Germany, let me tell you that for 10 Euros LESS per month I get 60 minutes of all-german-networks free calls and HSDPA flat-rate included (HTTP only, 3.6mbps)

If you want a flat-rate (5GB) 3G data package with the iPhone, they expect you to pay for 1000 minutes of voice calls too and hand over 89 Euros per month. Also note that the intermediate M and L offerings will cut your bandwidth down to 64kbps if you go over either 200MB 300MB or 1GB (respectively) of data usage. Pathetic!

n82+ = BEST!

One could take the jailbreak route of course but apart from it being difficult to do with the new activation rules, expensive and  time-consuming, it comes with a huge amount of risk. It’s not something I’m even interested in trying. No. I’ll stick with my solution of smartphones with good photo and video capabilities and combine it with a Gigabyte M528 for some real mobile Internet action. I’m even thinking of adding an Acer Aspire One to the kitlist and going for the full-on, no-compromise, high quality, three-device mobile strategy!
