Sigh....so I went to the Tampa Apple Store with my MBP last night as it was giving me trouble. Guy at the genius bar tells me that the logic board is dying....and I'm out of warranty. While it's not terribly expensive...it's only a year and a half old and I baby it, so it's frustrating. Note to other users who are sitting on the fence about getting an Applecare extension....DO IT! And also...the minute you suspect something's wrong with it....take it in for service. I thought it was acting up....and then it goes especially haywire when the warranty runs out. Oh well...such is life!
