My Zen Micro's battery has been dying a slow death for a while now, and it's time I upgraded to something else. I'm looking for 8-16G, dependable, long battery, no software hassles... Ipod nano doesn't impress me. I've been considering a Sony or a Sansa, but am open to all feedback. I use it at work, and may use it in the car, if I can get a decent transmitter solution... I don't need anywhere close to 120 gigs, and touchscreen really isn't a need, per se. Under US $150 would be nice.
