I love this thing. I know I went against the Buyer's Guide and all, but I figured I had better buy one now before I spend the money on something stupid. This is my first Mac and I'm in love. LOL! I got the base 15" with the 7200 RPM 200 gig HD upgrade. I've been on it for an hour and I haven't had any problems. Anyway, I just wanted to let all of you know!
