"Apple can plainly attest" ?
You mean I didn't buy my Macbook Pro because it had more memory, a faster processor and video card than contemporary notebooks in its price range/size. Also a gorgeous screen, a backlit keyboard, an accelerometer protecting my data by parking my hard drive's heads in the event of a fall, a magnetic breakaway power cord, awesome battery life, and a aluminum unibody holding it all together weighing in at only 5.5Lbs? Don't forget a UNIX-based OS with a largely consistent, beautiful and lean GPU-accelerated UI (read: doesn't require a ridiculous CPU+GPU combo to simply present my interface like some other UIs). Several aspects of the OS are empirically "better" than the competition- which is probably why the competition has spent the better part of the last 10 years duplicating functionality in OSX from the UI down through the frameworks. The OS + beautiful and capable hardware make an Apple computer a killer package.
I'm a software engineer with a computer engineering degree and I could hardly ask for a better development platform. Apple makes, on the whole, the best of the breed when it comes to personal computers and you need to compare the complete package (OS, build quality, tech specs, weight, battery life, etc) if you are to compare apples to Apples. Pun intended.
