So will most Laptops? and a Macbook Pro or standard is hardly big.
As for the post after, Mac for gaming = fail, get a PC with a 8800GT, Core2Duo and 2Gb ram. Sorted and no Mac £2000 or more is going to better it. (about £650 or so for the whole PC minus monitor I'd say roughly)
Actually, I have a dell laptop I carry about which work gave me. I want to take my Mac to work too and it currently doesn't fit in the bag with the dell. The Air would.
I understand your point about gaming, to be honest I probably will go the PC route, I do miss building them, a Mac Pro looks so pretty though!
