content: I loved mp3 players that used AA battery. iRiver T10 was the best mp3 player I ever owned http://ecx.images-amazon.com/images/I/41XBFJ9TERL.jpg I loved to just put extra battery in my pocket and to have 20-30h playtime in it (not kidding, sounds like a dream with iPod). Even travelling to most remote places there is at least one gas station selling AA/AAA batteries.  If this product was sold just with a bigger capacity or SD card reader, I would jump on it. Is there some player like this?
