"The spin here has been that it's somehow bad that most IT professionals won't jump to Windows 7 in the next year.
However, Windows 7 is still in beta and hasn't been released yet. Of course, 84 percent won't upgrade to Windows 7 in a 12-month time frame. If you go April to April and Windows 7 is launched in October-ish, that means IT pros would have just six months to make the leap. In the OS upgrade world, that speed just doesn't happen.
Cast in that light, the figures in the pie chart to the right actually look pretty impressive to me.
So within two years, 59 percent of IT pros plan to upgrade to Windows 7. The good news: that's some pent-up demand. The bad news: Vista is the reason there's pent-up demand." – Alan Cheslow
