Mine's an 'MPman', just a cheap one, 1gig memory - it does me fine, I've got no real complaints about it, and to use it, you just drag music files onto the icon, same as moving files about on your PC...

tbh, I think that more than 1gig is unneccesary (sp?) for music, mine fits about 10/15 albums on, and I can't see ever needing more than that... if you want videos etc, you might want more, but otherwise, IMHO, it's really just an extravagance.
