...and an industrial grade-aluminum enclosure (to say the least), an 1100 watt PSU, and super, super, super clean wiring (really, non-existent wiring (except for the GPU power). If you find a PC with these, and the aforementioned features, pre-built, chances are you'll pay a good premium for it.
The thing that's hard for many THG wintel-promoting enthusiasts to wrap their brains around is that with Apple you are paying a premium for design. How much is design worth? Well to a lot of people its worth quite a lot. ...and we can't argue that Apple is making money hand-over-fist and I can't believe that everyone that buys an Apple product is an ignorant dumb-@$$, because they are doing something that allows them to make the money necessary to purchase these products. See, most Wintel PC manufacturers don't offer a design that they can charge a premium for...their designs are me-too offerings. The good thing about that is that you're not paying for their design, only for the hardware, and the more typical markup.
It comes down to what's important to the average consumer. Design does seem to be important. There are plenty of things people pay extra for because of their brand/design: Cole Haan, Gucci, Movado, Maybach, Louis Vuitton, Crocket & Jones, Apple, Breguet, just to name a few.
Apple is the only (or at least one of the only) large PC manufacturer that charges a premium for its design. Its the only one that can. Dell tried with the Adamo...didn't work out too well. ...and of course this is distasteful to the do-it-yourself general enthusiast crowd at THG. ...who can build a nice, even attractive, machine at a fraction of the cost.
I know many wintel-toting enthusiasts don't like OS X. Okay, to each their own. As someone who's certified in Windows, I can say I love OS X. I get to come home to machines that are not only fast and functional, but that are really fun just to use. Its weird. MS has worked hard to capture that and with Windows 7 they're as close as they've ever been because Windows 7 is, indeed, awesome...but, to me, not more so than OS X. Not better, just different.
