well if it wasnt free I'd say maybe but me and a couple of guys chipped in so I only paid a little and we shared it so for me it was worth it, but If you play ALOT of mp3s on your Axim and thats a main thing you use it for I'd say that you might wanna spend it on pocket music. I havent found a better player so far.
Heres a pic of the skin I use right now:
Bah who wants winamp anymore :D
