I owned one for nearly two years I think, then decided I had too much stuff, it wasn't being used so I sold it to a member here. Yes, it was heavy, I mean REALLY heavy, but the 17" screen, and the top end cpu made it quick. I ran Logic X on it and it never pinwheeled or let me down. I had just bought a new MBA at the time and parted with it for that reason alone. They'll never make another large screen laptop, but I do miss the old best a lot.
