I've had my MBP (in my sig) for 2 months now and I love it to death, but I really wish I got a MBA. Maybe it's because everyone on campus has the exact same computer as me, or maybe it's because I never use any ports other than the mdp, 1 usb port, and audio out. Maybe because I realized the most pressing thing I do is watch HD videos and other not-so-hard tasks. Who knows, but I would trade mine in a heartbeat for a MBA.
