Directions in UMPC-land

> Battery life is the achilles heel of mobile devices; some kind of
breakthrough in power consumption or energy storage needs to happen for 
big strides to be made in this area. Because of weight considerations, 
today's UMPCs tend to have small batteries and three hours or less of 
battery life.

N810 idle standby time is over a week on full battery. When you're not 
using it, just lock the screen&keys (with the lock key) and put it to your 
pocket.  I think UMPCs could indeed improve their battery usage (although 
they have more power and larger screens, they have also larger 
batteries)...
