Seriously:
MP3-Player (NOT harddriver ones):
- 2 hrs playtime
- very small and light
- no skipping
- low battery usage
- decent quality
- music exchangable (for much extra money though)
- possibility to fix it to your clothing (dont need to feel it bounce while doing sports)
CD-Player
- 01:20 playtime
- huge and heavy
- skipping (if not, higher battery usage)
- high battery usage for laser etc
- perfect quality
- music cheaply and easily exchangable
- has to be in your pocket -> jumps up and down while jogging, very annoying
I think we have found a winner for sports...
And still, I suggest you get yourself a MuVo... Why?... Because it's ****ing small and for the above reasons
