I've often thought that any operating system without virtual desktops / workspaces is for all intents and purposes crippled. It seems that OS X is getting some in the next version, next spring.
It's nice. I guess. It's too bad Linux has had the same thing for over a decade. And in Linux it's far more powerful and far more customizable, I'd be willing to bet money. Oh, and Linux doesn't cost $129.
I did buy a Mac last year, and I tried to use it for a while. There are some things it's really good at. But I found that anything it could do, I could do in Linux. It may not be as pretty in Linux, but it sure works. And there are tons of things I can do easily in Linux that are hard or impossible to do in OS X.
The appeal of OS X is that it's polished and it's marketed really well. Linux is not polished; use it for ten minutes and that will be obvious. I use Linux exclusively and even I will admit that Linux is a God-awfully ugly beast. Well, it may be an ugly beast, but it's an agile, intelligent, and mightily powerful ugly beast. I'll take power over polish any day.
In the end I gave my Mac to my parents. I found that I never used it anyways.
(In other news, Windows still sucks.)
