Ok, I think I've decided to buy a 6GB iPod mini, which would be my first iPod ever. It will be pretty much full, but I think it will be a good way to step into the iPod world and then I'll get something better in a couple years. My question is, what are the must-have accessories for the iPod mini? Firewire cable (is it really faster than USB 2)? Do I need a dock? A case (does the mini need one)? Should I get APP if I'm only keeping it for 1-2 years? What accessories are worth it for the mini?
