yes, but the k800i has afaik a dedicated hw codec for music, so it would  
consume comparably less power for that.
and 2h is pretty much time.

pretty much. i for one load my fr mostly via ub at work and my impression  
is, though not backed by any formal analysis, that when loading via usb  
(ie 500mA) the battery lasts longer than with the wallcharger (1000mA).

well, recent kernels (.28 notably) have a reputation to be far more  
advanced in terms of power saving, so, yes, it is imaginable that the  
power consumption will improve in a not too far future.
but bear in mind that a device like the k800i is designed for a very  
specific range of use and thus could be made very efficient, powerwise --  
any general purpose device suffers from the compromises made.

well, depends on your schedule, doesn't it? getting up, heading to tha  
bathroom, having breakfast (or lunch, since you're a student -- though  
that would rather be in the cafeteria or so) ... pretty much time to  
charge the fr in the meantime.

what's wrong with that? you got an alarm clock already, did you?
