It's so rare I forget.
And what surprised me about the Sony PRS-T1 is that you can't change the sleep/power settings. It has fixed settings.
1. Go to sleep after 30 mins
2. Power Off after 3 days!
That almost suggests Sony's engineers know just what you suspect @Peakcrew.

That's impressive! Even allowing for the fact that Sony might have the inside track on battery technology (I think they have a battery manufacturing arm), that is good.
There will always be a difference between booting from off and rousing from sleep, because the reboot requires examining the database etc and doing any updating. However, the KT does seem to have a marked difference - 1-2 days shorter battery life switching off every night and rebooting the next day (never recharging at less than 25% on the meter).
The KT's power use seems to be worse than the Jetbook I had, and that had a TFT screen, which uses more power than e-ink.
