Well, right now a big chunk of computer users, are the young-ish gamers who surely don't know any better and will mostly switch to the coolest looking newest product, others such as hardcore/professional gamers who are interested in performance will probably stick with XP for now, as will the majority of people who generally know what they're doing when it comes to operating systems and computers in general. As for the latest computer not running it will like 386's ran OS/2 sluggishly, quite honestly the user in this day and age has a big broader spectrum of possibilities, given enough funding you can build a PC with 2 very powerful CPUs, two (or is it four now, I haven't kept track of the latest technology) very powerful video cards, 8 Gigs (or more?) of incredibly fast RAM, and hell even hard drives are coming close to a terabyte in size, and are damn fast too, however will the average "good" computer be able to run Vista? probably not as smoothly as Microsoft or the end user would like, but that's how new things are, right? -Lev
