LOL.. come on, you are still in BSD age.. take a look at ubuntu and then say!
This is attracting a lot of downvotes, but I'll restate what I said in more certain phrasing: If your operating system doesn't support my drivers without my having to do work, then you have failed to make your operating system easy to use. Say what you will about Windows, and I'll say a lot, it has never failed to give me audio/video, which Ubuntu has failed to give me every time I've used it.
Moreover, OS X also has numerous problems with peripherals. I bought a camera, standard usb camera sold by the millions, and there are no OS X drivers for it. I spent hours scouring the web and installing various programs into this location and that location. Supposedly those drivers support some cameras, maybe even mine. But no, to this day I cannot use skype video on my Mac Mini. On my Ubuntu partition, it works with 0 configuration. Plug it in and I'm done.
Another example: a shared printer. In Ubuntu jaunty, there's a brilliant dialog that automatically finds and sets up a shared printer with a few clicks. My friend Jeremy tried to set up the same printer with his Macbook Pro, and he asked me, we poked around, couldn't find it. We got a cryptic error message that said something about 'could not find bla...'. We tried for a few hours searching online to no avail. Today, he goes upstairs to physically plug in the printer directly every time he wants to print.
He tells me that for most Mac problems you have to spend a few hours searching online and you might find some blog post where someone mentions a trick. No, OS X is where Linux was 10 years ago when I was using Debian. Worse, because Debian always had apt-get, so I had lots of good free software at my fingertips. Ubuntu is far ahead in terms of being painless, and it improves every 6 months...
So if hardware is not a problem, it comes down to the software. Everyone uses the same web browser on all three platforms, so it's not that. Linux has better terminal editors and support for programming. (I ditched OS X after never getting emacs to work right.) Nautilus and Finder are about the same, although I do not like to use a GUI for managing files. Linux lets me choose, OS X forces its opinion on me. (I also don't like manually arranging windows; OS X forces me to do that anyway. It doesn't even have working "maximize".)
Anyway, I spend maybe an hour every two weeks caring for and feeding Debian, and that means all my software is always up to date. On my OS X machine, I spend less than that, but every piece of software I have is outdated since it is too annoying to manually update everything.
YMMV, but Ubuntu is probably a fine OS for 90% of computer users (especially with OO.org 3).
