Pro or regular
Are you talking about the PRO or regular Macbooks? Because your subject says pro and your question only says Macbook.
My two cents are that you should get the MBP Classic for the screen, graphics card, or adaptorless firewire and DVI...
You should get the MB if you're concerned about portability.
I was leaning towards the MB until I found out that even though both screens are backlit LED, the MBP classic has a much brighter and higher quality screen.
