Anyone have any idea of the dimensions of the slim dvd drive in the MBP? I've heard it is thinner than in previous versions. Are they a standard size? Having just replaced my hard drive in my 12" Powerbook, I noticed that it looked fairly easy to change the dvd drive too. The reason I ask is that the new MBP, unlike my current PB, appears to have a Panasonic dvd drive that won't do multi-region - not something I want at all! Ideally I'd like the replace it with a non-panasonic drive. I don't care if it writes dvds or not. Anyone know about laptop dvd drive sizes?
