i have a iPOD mini, i love the setup and i even have a 4Gig stil small and doenst show anything , slight scuff on the wheel but thats it. I was lookin at the nano, but its still up there in price, ill wait til it drops more. I think the mini has the best casing for durability also. the older bigger ones an the nano have more of a glossy casing so they might scratch easier
