The basic platforms of the Macs and PCs are the same. Intel, x86, in a sense they are the same. This you cannot deny. But, there are still chips and such that makes it an Apple computer. This is obvious, because if they were the same, you could throw in the tiger disk in any computer and boot it up out the box, or vise versa with Windows.
some of you ppl are freaking blind that you think that MACs are same or equil to PCs , makes me laugh. seriously ..
But I do have one theory that some you might not agree with, or agree with. Why we have Osx86. 2 reasons. One, price. Base Mac is $599. The mini, base computer, well you can spend maybe $100-$200 less than the mini. PRICE is one reason, another is customization. Video cards for one, people who want the G80 chips in a mac, or the Core 2 Extreme desktop cpus, or the quad cores, Overlocking goes with customization.
