Windows 7 is a great operating system. I run it on my PC, and in Parallels on my Mac. It's not the best OS however, that still is OSX or some of the other Unix/Linux flavors, like Ubuntu.
The reason there sales are so high, is corporate sales. Millions of companies are still on XP. They skipped Vista, and now that 7 is out, they all upgraded there volume licenses.
I think the best thing about Windows 7 being so good, is we can stop with the fanboy BS now, and just use whatever OS we like. The days of having to defend a piss poor product (thus hearing the wrath of the community) are over.
