Hi SpyPirates,
Whereas Vista was the most compelling reason to try a Mac, Windows 7 is the most compelling to stick with Windows.
I have been using the Release Candidate of 7 for quite a while and am totally impressed, along with millions of other users. It is not as resource hungry as Vista is, it has superb compatibility and a host of other features that you can access from
here,
here or a multitude of other places.
Cheers.
