Learning from my mistake of keeping my MacBook Pro for four years (I discovered the hard way that I could have upgraded my $2500 Unibody '08 MacBook Pro every year and effectively spent less money in the process. Now, I'd be lucky to get $600-$700 for it. So I plan to upgrade my to-be-purchased-soon Retina MacBook Pro every year.) The issue I run into with upgrading every year is that if the first upgrade of the year is not significant (Apple has been known to release up to two upgrades in a year) or is not released before the warranty of the brand new system from a seller who decided he doesn't want it I am purchasing expires in July, then I will be stuck with a practically non-serviceable system for a few weeks/month where something could break down even though that is rare - but would still be a costy repair/value hit. Thus I have to wonder just how much value AppleCare adds. Perhaps more than the cost of it for the fact that the system can't easily be repaired and the buyer won't be able to add it on most resold systems since they'll be out of the initial warranty period. What do you guys think?
