My mate wants to buy an mp3 player but because he wants to use it for sport (rowing, running, cycling) hes looking at the iPod Nano 4gig. Thats gonna set him back about £180 but that seems a bit silly as you can pick up 20gig players for £150 nowadays. My question is, are there any hard disk (about 20 gig) mp3 players out there that can be used for sport without them skipping? Im thinking particularly of the creative zen micro 20 gig. If not, what are the best (read: cheaper) alternatives to the ipod nano in terms of quality and storage capacity.
