I just signed up to also voice my support for an AA powered mp3 player, preferably with a memory card slot.
Why? I want to be able to throw the player and a few spare AA batteries in my bag. This gets even more important when I go on a trip with multiple devices that use AA batteries, like my gps and headlamp. In this case, the spare batteries work for everything instead of only one device, and the batteries in each of these devices can also serve as spares for the other devices.
It’s unlikely that I’ll buy another Sansa mp3 player, or any standalone mp3 player, unless it runs off an AA battery with the potential for lots of storage.
