If you get a good 'un, Apple boxes last forever.

But once one starts failing, it never stops.

I was very grateful for the AppleCare on both my iMacs (both needed display, optical drive and discrete GPU replacements) - but my Mac Mini never missed a beat, and neither did my old G4 Digital Audio.

All my iPhones and iPods (2 x 6S+ (current - me and the missus), 1x 3G, original iPod touch, 20GB iPod Colour, 4GB iPod Nano) have been unfailingly reliable. Well, the 20GB was until I dropped it, which buggered the disc. Still, sold it on eBay for £100 - as spares!
