Netbooks?
I would figure the big problem is how hard it is to find a netbook or low-end notebook with Ubuntu or the like on it, and how poorly Windows runs on these low end machines. I would NEVER buy one of these low-end Windows machines! Also, does AMD have anything good for these machines? The Atom is so low-powered (and despite all the people running WINDOWS on it and claiming it's too slow, it's not slow if you run an Atom Linux distro like Ubuntu netbook edition), unless I've missed sometihng AMD has nothing close to that low power -- a few of their new chips are supposed to be close but those are just coming out.
