Ipod (any gen, make or model)
Seriously, I've blown through too many of these so I finally gave up. Bought a used Zune, never gave me problems.
The ipods I've had have all broken numerous times. I was at least able to swap them for new ones while the warranty was in effect, but now it's out and I'm done. Fuck. Apple.
Shit-tastic products for fanboys.
