My favorite feature here is that this player uses one AAA battery, so you can change it on the go if you have to! None-the-less, it does charge when plugged into the comp.
Doesn't hold a whole lot of songs, but I like to change out for a fresh list now and then anyway and unlike iPod these don't require a program to load songs-even though one is provided.
I've been running with it, working with it and training with it. It's small, VERY easy to use, the buttons are easy to find without looking and the preset EQ's are actually pretty good.
Only thing I think it needs is a micro SD slot, that would make it all out awesome. None-the-less, totally worth it's money.
