The top-of-the line G5 series actually compares quite well to similarly configured windows systems. The low end G5 (which is not a good deal, IMO) costs $2000. The mid range 1.8 Ghx comes with wayyyy more of everything as compared to the 2000 model (double the hard drive space, double ram, faster bus, better pci support, etc..) but only increases in price to $2400. The dual 2 Ghz model has a better graphics card, and even faster FSB, increased clock speed, and 2 processors, and it will set you back $3000. If you go to the dell website and configure as machine as close as possible to the dual processor g5, the G5 ends up being about 300-400 dollars LESS than the dell. I use both PCs and macs, and I can honestly say that I would choose a mac in any situation. The sheer reliability is a given, and I have never had to wonder if the mac would be running if i left it on for a month rendering. I KNOW it will be fine. I find that working in the windows environment makes me have to "deal" with the computer all the time. On my mac, I feel that the computer is there to complement my creative process and stay out of my way while doing its job. OSX is an amazing yet simple OS, and it's easy for anyone to pick up on. I suggest going to an apple store and just fiddling with a few of the macs they have there. The employees do not push products on you, so it's great to get an objective opinion and get any questions answered. My guess is that when you try it you will like it, most likely more than you had been expecting. Windows is not a bad OS, it is just, IMO, the mac offers an environment more suited for people with a creative flavor. It keeps out of your way but has the tools you need WHEN you need them, right then, and it works.
