I never use hand helds for more than 2-hours, and if I ever do I'm at home so I'd just hook it up to the wall. So what's wrong with this? Nothing to me.

The only time I'd really take it around for more than 2-hours would be to play MP3's, that's assuming I don't buy myself an iPod or something similar. 10 hours is defenatly a decent amount for playing music outside.

In conclusion, battery-life has no effect on me.
