Windows 7 will be faster than Windows Vista on any machine. On most netbooks, I would have no hesitation about running Windows 7, particularly with 2 GB of RAM. The slower prpcessor, though, is a factor in favor of running Windows XP or Linux to try to squeeze every bit of performance out of it. I would still try running Windows 7, perhaps use the release candidate, which is still good for a few months, and then buy Windows 7 if the performance is acceptable.
