I'd feel bad if this option wasn't discussed, but i highly recommend squaretrade over applecare for macbooks/laptops. Squaretrade offers accidental damage, whereas applecare does not, but also has a small deductible.
And since laptops are inherently mobile....dropping/damaging it is a lot more likely.
Here's the price breakdown on 3 years on the lowest and highest rmbps.
13" rmbp, $1299. AC is $250, ST is $230 w/ $75 deduct, or $350 no deduct
15" rmbp, $2499. AC is $350, ST is $399 w/ $75 deduct, or $460 no deduct.
So, you have a laptop and drop it. AC says your out of luck. ST says $75 and you get a new laptop.
