I don't have the money to buy a MAC, so I use LINUX instead and am typing this on a machine i built from the ground up (a dual processor Celeron with 360 MHz CPUS overclocked to 550MH. I built this machine over two years ago -- it runs 24/7 but occasionally hickups under heavy load from a badly sized capacitor -- a well know BP6 flaw! -- from the ground up (well, I didn't actually smelt the silicon from fine sand, etch the chips, or wavesolder the ABIT BP6 motherboard, i must admit ;) With a MAC, you don't have the same hardware options and pretty much must take whatever steve jobs in his infinite wisdom doles out to you, even more so than what bill gates in his infinite lawyerly wisdom decides where you want to go today if you are enslaved by Micro$oft...
I must also say that of everyone I know who has a MAC (about 6 or so) NONE had to pay for their own machine, and every one of them (sorry, MAC fans, i'm just describing the MAC owners I happen to know!) is a bit of an elitist.
Now, if I had to actually use Windows caca-ware and didn't have enough computer skills to use Linux to do my work, i have no doubt i'd be using a MAC as a soothing alternative to M$ idiot-ware
(whoops -- i'm transforming into a LINUX elitist!!!)
