I used Vista for almost 3 years, and consider it superior to XP which I also used for a lot of years. I now have W7 on every computer I own, and most of the time that is a great system the occasional BSOD overlooked. I will certainly consider updating to W8 if it seems to offer significant improvements from W7. Since W8 is still in Preview edition, I have not had a chance to get acquainted with it. It is probably still a year or more away from release. Most of the time, the upgrade from on MS O/S to another is in the $100 range. For me at least, this is not significant. Especially if they offer a 3 computer update in that price range. W8 is the O/S that will allow Windows vendors to compete with the i pad, so a lot of what is in there will be slanted toward that.
