Apple is great at manufacturing and logistics though, so the parts are probably pretty cheap for them even though they're also good quality (well, likely better than you'd find in the aftermarket or on eBay). The repairs they do are fairly simple, so combined with their ability to control the experience and make sure it doesn't suck for consumers helping their brand, it's another revenue channel for them. Edit: even if they're losing money on every repair, it might be worth it to them to give people the peace of mind of knowing that they can "take it back to where they got it" to have it fixed if anything bad happens. That's not a common thing with electronics these days.
