I'm sorry, I saw this thread and I just had to post in it with all the idiots in it.
Okay, first of all.
Only morons or little kids get viruses on their computer. Seriously. Even if your a moron, Windows Security updates, combined with an anti-virus and mozilla firefox have caused even my 6 year old sister to NEVER get a virus. Before when I didn't have an anti-virus, I only got a virus ONCE at the age of 8. You know what I did? I did system Restore, and my computer was fine. Stop calling it a LOL VIRUS MAGNENT!! If you are a mac fanboy simply because you didn't know how to remove viruses, fine then, that's okay. But don't go going around saying "HUR DUR WINDOWS HAVE VIRUSES ROFL!!!!." Macs are for people who don't know how to use computers well.
Secondly, Macs are overpriced, period. The Mac Pro is also useless, because I assume you want to use it to host servers, because the processor can't be used to play any games, not to mention the graphics card sucks. And, folks, please don't use any Windows or Mac OS's to host a server. Any decent server admin would use linux.
Thirdly, your OS isn't revolutionary. At all. It runs on a UNIX system. That's why it's more stable, because it runs slower then Windows. Apple computers couldn't even multitask until they hybrid'd someone else's OS, which is Unix.
"So what ARE Macs good for then, Belleraphone?"
Macs themselves are over priced, like I said, I can find a more powerful one for a cheaper price. But the OS X.....
The OS X's main advantages would be "multimedia" kind of things, since Windows is better at Work and Play, OS X is also better in security, but only because not as many people are writing viruses for Macs. (Google Mac Virus.) OS X DOES crash less then Windwos Vista, but Vista runs faster then OS X, (Assuming both computers have equal specs.) Windows 7 doesn't crash at all, I've been using the BETA of it for about 6 months, the only time it crashed was when I tried to code a program, and it was resolved in under 15 seconds. I didn't have to restart my computer or anything.
Overall, in terms of the OS, it's really a matter of opinion. OS X is for less tech-savvy people. You can also install OS X on a PC, just sayin'.
If you buy a mac because it's "thin" and "Sleek." HP also make thin, powerful laptops. That's all I have to say.
