I primarily use my computers for my art and the internet. I gave up on PC (Windows) 3 years ago after losing countless renders and sometimes entire files to Windows inability to perform to my expectations, or should I say CRASH. I have a Mac G5 and an Intel Macbook. Both perform very well and I can render in Bryce, create in Vue, listen to iTunes and surf the net all at the same time with no noticeable loss of performance. I am not a gamer, and Mac lags in that category. I guess you just have to consider what your main use will be and go in that direction. BTW, OSX is very simple to learn, so don't let that scare you off.
