An iPod classic, if it matters - the rotary wheel still spins stuff, and if I click on it the screen lights up, but the "Menu", track advance and repeat, and play/pause buttons don't do anything.
I'm pretty sure I still have the receipt and that it's less than 2 years old, but I don't remember if it comes wiht a 1 year or 2 year warrantee. How repairable are these things? If I bring it into the nearest Apple store, will they be able to quickly fix it, or am I on the hook for a new one?
There is a factory restore function in iTunes. That is where I would start.
