From the tech savvy, which is the best "value" MP3 player out there these days? My wife and I are long time iPod users (1st gen Nano's and 2nd gen shuffles). I played around with the idea of buying a $500 iPod Touch 32gb but figure I am probably overlooking some other good options. For example, having a FM radio could come in handy I suppose. I also wonder if they will come up with a XM radio/MP3 player at some point. So what's new out there?
