The thing about OSX is that I'm not sure I actually like it. It's the prettiest OS I've ever used, but I almost never use my Mac anymore.
I got a Mac laptop a few years back - I got it more for the physical design than anything else. It was a little weird using a Mac (after rarely using them since the early 90's), but I got used to it. I also clocked a lot of hours on a more powerful desktop Mac at work. I'd say that's given me plenty of time to get used to the difference between a Mac and a Windows box.
Windows used to piss me off to no end - constantly crashing, making me lose my work. It's been a while since that's been the case though - of course, I'm still an XP user with no intent on migrating to Vista in the near future. I've got a lot of the "cool" features turned off - no transparency, no fade-in boxes or menus, and a generally stripped-down interface.
On the hardware side, I love Macs. Except for the prices I've paid for them, I prefer all my Mac hardware to Windows (except for mice - a single-button mouse is a good example of art over function. I quit using single-button mice on a mac years ago, and hate being stuck on someone else's).
But the operating system, while pretty, just doesn't do it for me - even after years of using it. The standard GUI is too simple to suit my needs, and it's advanced interfaces aren't so well designed as the alternatives. I got to like both KDE and Gnome quickly (they just suffer from a lack of decent apps to make them worth my using them), but I still see Macs, software-wise, as belonging in the domain of unskilled users, and techies who use them just to use a Mac.
All the same, I hope Macs have a bright future - if nothing else than to drive their competition.
