Running linux comfortably on the 12" would be a real challenge, and I wouldn't count on it. All the new stuff in the 12" and 17" is not necessarily well supported, and the geforce video chip definitely isn't.
The older 15" is great though. As to why anyone would want to use linux, well, linux might become pointless on the macs once they have a good, fast and working OSX port of X11 and the matching apps, but it certainly isn't the case yet.
