Personally, they make the stuff I need to get my job done better than anyone else. Really, other than Office, I don't need anything else from MS. Their office suite is by far the best out there. TBH, I really like Windows 7, but OSX would be fine for my needs, too. I'm not much of an OS junkie, so I just stick with Windows mostly for compatibility/price reasons. To me, the OS is just "there," and I do my work around it. For my usage, Windows is unobtrusive, therefore I can deal with it. I can't say the same, in my personal experience, for Linux (that, and there's no MS Office).
