I received mine last week, loaded a few tracks on to it no problems, played a few tracks and has never worked since. I can load stuff on and take stuff off. the files will play on the computer with media player. but won't play anything through the earpiece & all options do nothing.
I wanted the mag so not to worried about the MP3s.
I'm very happy with mine, it did take quite a while to load it with 2gb of music, but once finished I'm very happy with the sound. I abandoned the included earbuds and replaced them with a fairly basic pair of Senneiser MX350s and the sound quality is surprisingly good.
Tried a wide variety of music from Girls Aloud and Pink Floyd through to Sarah McLachlan and Johnny Cash and decided to dump my iPod Shuffle for good.
