I am a huge mac fan, but they are virtually the same computer now, with the exception of the operating system. The only legit argument other then the os is the cpu (ppc chip) in the older mac, which has its positives and negatives just like the intel chip. It really depends on what you are doing with the comp. What really bugs me is when you get someone who is raving about how good their macbook pro is for editing; A) they are usually first time mac owners who really have no idea and B) its the same fucking chip as in a pc. You can't tell me that it renders any faster or is better. Sure you have final cut pro, which is an extremely good program, but atleast back up your argument. I could go on forever about the pro and cons of macs and pcs, their is so much to debate.
