my experience with apple care wasnt so great. especially with a laptop, which you carry everywhere , and you are bound to get scratches and maybe a minor "dent" on it. The moment it has what they consider "physical damage" on it, it voids all warranties. Mine had a failed logic board, and a minor dent by the cd slot and it did not cover. 1200$ estimate between parts nd labor to fix, and 350$ wasted on apple care.. so if you are a real careful person, then maybe yeah. I didnt fix mine, im waiting on the new MBP to come out and i will not be getting apple care on it.
Edit: My previous laptop wasnt unibody, the new one's do look more sturdy. you'd need to research.
