David Berlind writes the best summation I’ve seen of the problem with Windows Vista:
Today, I’m a user of both Windows XP and Windows Vista and while I remain convinced that Vista is a better OS than XP, my usage of XP serves as a constant reminder that when it comes to getting my work done, I’m not getting it done any faster or better in Vista. In fact, because of the way several things have been moved around in Vista, and because of the way Internet Explorer 7, in an effort to protect us from ourselves, locks up the Web in a chastity belt, I often find myself being slowed down by Vista. It may only be a matter of time before I get used to it (and figure out how to reconfigure IE7 with the necessary wiggle room). But the bottom line is that (a) I’m definitely not more productive and (b) if I finally get to a point where I am more productive, it won’t be by much.
There’s almost nothing that I can do with Vista as an operating system that I can’t do with Mac OS X or even GNU/Linux. In fact, with both those operating systems I can actually do quite a bit more with the operating system itself.
Where Vista scores points is in its interface, which I’ve grown to prefer to the Mac, and in its application support. If you want support the largest pool of application, then Windows is the way to go – as it’s always been. That’s not to say that OS X and GNU/Linux don’t have star applications – they have many – but the broadest selection is on Windows.
