Jenn, now a Willcom D4 owner as well as an SC3 owner, has her first impressions up. As expected, the battery life isn’t good at all with the tiny standard battery returning 1.5 hours of use. Its efficient of course, but that’s not really enough is it. I really don’t understand how any OEM could convince themselves that it’s acceptable to expect people to buy a second battery.

Apart from that, the device seems to be performing well enough with Vista on the 1.33Ghz CPU.

The Willcom D4 never felt right to me from the word go and this review doesn’t change my opinion.

D.F.J – Direct From Japan, an exporter of mobile solutions direct from the Akihabara district have a Willcom D4, one of the neatest ultra mobile PC solutions we’ve seen yet. I’ve been in touch with DJF today and they’ve been kind enough to send over some first-opinions about the device. Before you read through them though, let me highlight one very important figure. Last week it was reported that the D4 was returning just 1.5 hours on the standard battery (7wh) DFJ report that this is under WWAN conditions. Running without WWAN and Wifi is a different story. We’re working on getting some better battery life reports out soon so don’t give up on the D4 just yet. Continued after the pic…

Once again, we sadly have to report that OEMs are trying to squeeze Vista on low-end UMPCs. I’m also hearing that ‘unoptimised drivers’ excuse again… [Deep breath…Gooosefrababa]

Akihabara have done some testing on a Willcom D4 1.3Ghz Atom-based ultra mobile PC which they say has a "Beautiful design, ergonomic, a well thought out keyboard, multiple positions, touchscreen…"

The device appears quite large in comparison to say the Gigabyte M528 MID and reminds me of the Raon Digital Everun which isn’t a bad thing because I’d be extremely happy with an Everun that used this design and ran Windows XP. Vista, however, is just going to end up embarrassing Sharp and Intel as it appears to do in the video that Akihabara have produced.
