u r right-- the vibration would damage hard drive based player such as ipod.
although, if u want to buy an ipod, then just buy ipod nano- which is flash based and it is suitable for biking and all kinds of acitivity and it is the thinnest and lightest player around so u won't feel its weight while biking.
--there are also other flash based players from IRIVER which are awesome, too in addition to CREATIVE mp3players
but i still prefer u getting ipod nano
hope this helps!!
Me and my buddies cycle a lot in the summer, (Canada), so we got new MP3 players recently for that purpose. I got a Sandisk flash player and one of my friends got a 30gb Ipod (I think it is a photo Ipod. It's beautiful.) My question is... is a hard-disk player suitable for cycling, or will the vibration damage the player?
