Well, the whole Mhz thing was really clever marketing because Motorola couldnt produce at the speeds apple wanted at the time. Now, as for sheer awesomeness, apple wins. How many other players are shipping a dual 2.5 Ghz watercooled machine as a standard item? nobody, thats who
Of course, the safety precautions are impressive too. I'm supposed to wear rubber gloves when handling anything with fluid on it, should the assembly leak. I should wipe up any spilled fluid with paper towels or rags and then dispose of them according to local ordinances, and replace anything that got coolant on it. Chances are its mostly water and antifreeze, but who knows what else is in that crap. With my luck, it'll make me sterile or something equally screwed up.
