I have 2 PCs at home, 2 at work, and a G5 mac at work. I turn on the mac about 3 times a year when someone brings me a Quark file. It was top of the line a year and half ago, and I found it slow even then. I build my own PC's with better stuff that Apple uses at a third of the the cost. It runs faster(I'm a designer running memory hog design software and RIP programs too), never had a virus(Avast rules), and between the 4 PC's the only time one of them crashed in the past year is because I kicked a cord in the back pretty hard and knocked the video card loose. Macs are good computers, don't get me wrong. I have nothing against them, but their marketing. To me, most of their appeal is to people that are trendy and/or anti-establishment, but in reality by buying a Mac for that reason is the exact opposite of that. If you are trying to be different and get the same thing that everyone else does, that makes you the same as everyone else. Kind of like trying to be a Hot Topic goth. Not saying that everyone that owns a Mac is like that either, so don't take it the wrong way. Vista(at least ultimate) is not the greatest OS ever, but not as bad as everyone thinks with the service packs. I only run it on one PC at home that I just built, because I got free Windows 7 upgrade which will come with any PC purchased in the next few months. There are actually things that I like about it, but I am running the 64 bit version. 18 GBs of RAM is nice. Get what you want though, you're the one using it.
