15: I got an 80 GB 5th gen back in 2006 and have worked the poor thing hard over the years. The drives aren't the thing you have to watch out for as they only spin up periodically to cache tracks into ram. Batteries though? Mines has been through at least 4 changes that I can remember doing due to me using the hell out of it. Besides that it's been jolted around, dropped more times than I care to remember, had stuff dropped on it more times than I remember, almost set on fire once, Stood on once and almost stolen by a small child. I've written at least half a terabyte to the drive over the years and the thing just won't die. Apple were a different company back then though, they built shit to last.
Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right.
