Toshiba R400: battery blues?

R400_main_2I noticed that Rob Bushway caught the BusinessWeek review of the Toshiba R400 Tablet PC. I read the piece and it looks pretty fair and honest. I did like the R400 when I saw it at the CES, but with a price over $3k for a fully-featured unit, it had better be a solid performer. From what I’ve read, it generally is except in one area: battery life. Ironic, since were just chatting about battery life in our last post.

Here’s what I don’t understand. Toshiba put a 4400 mAh battery in the venerable ol’ M205, but only a 4000 mAh batt in the new R400. Couple that with power-saving features in the R400 when compared to the M200, like a slower Core Duo CPU and an LED backlight; I’m left wondering: why is the R400 delivering less battery life? Sure, Vista and the Edge Display may have something to do with it, but I’m reading reports of 1.5 to 2 hours of battery life, which is surprising; I used to get much more than that on my M200. Of course, if Toshiba wants someone to test the battery runtime, I’m game….. ;)
