I didn't lose anything. All intact. I'm not defending the decision but it should have been clear Apple was abandoning the original AppleTV when they clarified that there would be no software update to support Netflix. Or AirPlay, as you can still stream to AirTunes from a Mac but I doubt you can stream from an iOS 4.2 device.
But this is on my MacBook Air. About 1,600 photos, all either dupes also on the main household Mac, DVD and Time Machine, or iPhone camera photos, backed up via Time Machine. On the household Mac, it's running iPhoto '08. If I can avoid it, I'll never upgrade that. It's stable, 4,000+ photos and a bunch of home movies are safe, and if I want to order new book options I can just import those photos into iPhoto '11 (or greater) on another Mac.
I find digital photography makes you paranoid unless you order prints of everything.
