<< The color ones eat up batteries like nothing else though. >>
I havn't really experienced this with my H3635. I played 2+ hours of MP3s and still have around 75% of battery left. Thats not too bad. If you really thing about it, you don't really need more than 5 hours of battery life/day. Unless you are using it all day to play games/MP3. As soon as you get back home/office, just stick it in the cradle and it automaticly charges. I understand if you are away for longer stretches of time, but you can get a car adapter, or bring your AC cord to the hotel.
