I have a new MacBook MB403LL/A (early 2008 model) 2.4Ghz, 2gb RAM upgraded to 4GB. My question: Would you get the AppleCare Protection Plan - Extended service agreement - parts and labor - 3 years ? It's a bit over $100 but is it worth it or are most problems fixable? And what kind of problems would this resolve? I mean, if my computer crashes... I could just simply re-install the OS right?
