I've had my 1st gen iPod nano forever now, and I'm really getting tired of it, mainly the fact that its only 2GB I would like to get something thats 4GB with expandable (microSD) memory. I looked at some iRivers b/c I heard they were good, but found only touchscreens. I need something more tactile that I will be able to change tracks on without looking. So now I'm looking at the Sansa Fuze + Rockbox. My main uses will be while I'm on my motorcycle or at the gym, so SQ isn't of highest importance, I just don't want it to sound worse than the iPod or have terrible battery life. All suggestions welcome. Thanks.
