I like the thinness and the unibody of the new MBPs, but I'm gonna have to go with the old one. The biggest thing is, I never liked the design of the black display bezel. I personally find it visually distracting and difficult to use. I've been using my iMac now for 3 months and I'm not yet used to the feel of it. Also, the glossy screen is something that I detest. It looks pretty while the computer is off, but once it's on, it's full of glare and it's downright ugly. So, by a narrow margin, I'm going for the old MBP.😎
