What do you do when it breaks?

Modern computer equipment is not designed to last forever. Computer equipment that is heavily used by a 4 year old is even less likely to survive. (I just was trying to talk in my pool/sandbox/mud/...!)

Are you going back up the iTunes computer too? Restoring backups relies on various moving parts. It's never a simple matter when operating systems and hardware keep moving forward. I'm not saying there's a better solution here, just saying it's non-trivial and fragile.
