Just bought a refurb'd 2.4ghz MBP and I love it....even the glossy does not bother me. It is a big laptop so if you are needing "portability" I would probably suggest the MB. The bigger screen on the MBP is worth it....and better quality from what I heard.
In my opinion i would have to say the unibody for two simple reasons...the keyboard because the keys are spaced and for a man with big hands thats more comforable the the old keyboards and i would say the placement of the super drive. I hated the front loadi g drive because when you had to load a disk while on your lap you would have to lift it up and all that. And when you burned a disk you would have to worry about when its done for fear the disk would pop and jam againt you and mess up the drive
