AA batteries dude, I saw your post before on the sandisk forum (I like sansa too, as most people here), but aren't most of those replies negative? I remember a time (Im old) when I was walking around with my walkman, and then the diskman, and after 2 or 3 hours the music was gone and that was it, also, I don't think many of us live that far away of a place where we can't just plug our players every couple of days instead of carrying a bunch of batteries, and if you still want to recharge those batteries, why charge them for a couple of hours if you can charge your player and it last for days, and it's easier to carry just the player and it's cable than the player, 2 batteries, another 2 spare batteries for the hours it takes to charge the other ones, the batteries charger and the bateries charger cable, and I'd prefer the space taken by 2 AA batteries to be for a bigger screen for example, I don't want to start an argument or anything, but I look at my clip+ and clip zip a big reason I like it is because of the size, if it had the size and weight of those batteries inside as you proppose it would like double the size, be heavy and it would last a couple of hours.
Soo, when is the m3 out?
