Just moving this discussion over to the "Computers" section... speaking as a guy who's heavily used Macs since 1986 (I held off until the Mac SE came out), to me, the operating system of choice is just a means to an end. I'm annoyed by Mac OSX, Linux, and Windows all the time. They all suck, they're all unreliable, and they're all evil. In more than 30 years of dealing with computers, I still don't trust them, and I use a whip and a chair to get what I need out of them.
Macs have been beyond being a PC for ages.
But Mac OSX gets out of my way better than Windows -- in my experience. When I use a Mac, the OS disappears and all I'm aware of is doing what I need to do. Windows and Linux just get in the way and annoy me. But most of the Linux stuff I get involved in is "purpose-built" software (like color-correction) that essentially just does one thing. I treat it like it's a color-correction machine, not a computer that does color-correction.
Anyway, my point is that Windows is still very useful, and there's lots of stuff I can only do under Windows. Or, if there's a Mac alternative, the reality is that the Windows program is better-designed, does more, has more features, or all of the above. Not everything is better on the Mac -- to me. A lot of everyday activity is better, but it's not 100%.
And I have to admit: Windows 7 (and the new Windows 8 ) are the most "Mac-like" Windows yet. I think both Mac and Windows are blurring together, to the point where it's getting harder and harder to tell the difference.
Note that there are many post houses who are very concerned at Apple's lack of information regarding high-performance Mac Pro desktop computers for editing, color-correction, and audio mixing & editing. Nothing has been resolved as of NAB, to my knowledge. I know of several companies who are moving away from Final Cut Pro and Macs for this reason, because they're concerned that Apple's profits from iPads and iPhones are diminishing the importance of computers and operating systems to the company.
For this reason, I'd say, "don't damn Windows today. Chances are, you may wind up using it tomorrow. And the more flexible you are in the current world of business and production, the better chance you have of surviving."
All just my opinion, of course.
