Wow, don't turn this thread into a Mac OS X/Linux/Windows debate. Join a forum dedicated soley to that if you must. Mac OS X, Linux, and Windows all suck. Mac OS X, Linux, and Windows are all good... It just depends what your needs are.
And please, don't bash Microsoft. Because of Microsoft, you have a PC. Because of Microsoft, Apple has grown. Because of Microsoft, you have TGC. If it wasn't for Microsoft, a lot of people here would still be mindless idiots. If it wasn't for Microsoft, there wouldn't be DirectX, and as you can see, DirectX kicks OpenGLs ass (DX 10, I haven't seen anything like that from OpenGL without having to use shaders, which OpenGL doesn't natively support (I think)).
So, with that said, you all need to go back onto the topic of VISTA. Not XP, but Vista. Vista isn't as bad as you all say it is, is the topic. Don't take another OS into account. If Vista meets your needs, post. If Vista doesn't meet your needs, post a REASONABLE argument, not what I've been seeing.
Cheers,
