I finally jumped ship and got my first ever MAC. The 2.3GHz quad-core Intel Core i7 model and I love it. I'm also a photographer and the 4 gig ram wasn't cutting it with lightroon ect. I got the crucial 16 gig upgrade and am now totally satisfied with the performance. Also using a Dell IPS pannel which is calibrated with a spyder4pro. No problems what so ever only wish I would of switch sonner.
