Windows 7 turns a year old this month, and 12 months after a successful launch, nearly everyone agrees that it is a huge improvement over Vista. However, despite this, the majority of Windows users are still running XP and have yet to upgrade to Windows 7.
Conceivably Tech reports that, though the number of Windows users still running XP is falling, it's falling at a very slow rate. Data released by Net Applications shows that Windows XP accounted for 76 percent of all Windows users when Windows 7 launched and this figure has fallen just 10 points (to 66 percent) in the last year. Though Windows 7's market share is strong and continues to grow, Net Applications data puts XP's overall September share in the OS market at 60.03 percent, down just 0.86 percent from the month before.
Conceivably Tech's Wolfgang Gruener predicts that considering XP's overall OS market share is dropping at a rate of less than one percentage point per month, it could take over a year for the nearly 10-year-old Windows XP share to drop to 50 percent of the overall market share. The data comes as we approach a particularly significant milestone for Windows XP. Microsoft's deadline for manufacturers shipping machines with Windows XP is October 22.

if you're good with computers and planning on buying 7 wait until service pack 1 is out, maybe even service pack 2. too many headaches with vista/7 to not want to go postal at microsoft corp every single day. wait for the hardware you need to be designed for windows 7 first and not backward compatiable with vista/xp as you'll pull your hair out.
Windows 7, though most of the time can be configured not to, does more for you... I am personally quite capable of doing it myself.
