I love how the car metaphor is always brought up, but seemingly is misinterpreted by the PC loving crowd.
I agree with above similarities. In my situation, I own both 2 Macs and a PC. I also own a Volvo and a Saturn. I definitely equate my Macs with my Volvo, and my PC with my Saturn.
Both drive down the street, and essentially do the same things (transport me and my family and my stuff). Which one is by far the better experience overall? The Volvo!
But wait a minute, my Volvo is missing some really cool things my Saturn has. A tilt steering wheel, cup holders, a sun-roof, fold-down back seats to access trunk-space, ability to open the gas cap cover and trunk from inside the car, etc. etc.
Do any of those added features make the Saturn a superior vehicle. No way. By the same token, a PC is not automatically better because it may have some added features. Also, just because both the car makers and computer makers share innovations and ideas with one another, is not what make the machine superior/inferior. It is the OVERALL experience that does it.
A PC may be able to do all the things a Mac can (I doubt it) and some here have said that a PC can do more (I sincerely doubt it), but that doesn't make it better.
But again, I appeal to the human side and state that it all comes down to personal preference and experience. Some people DO like PCs more (though I'll never understand why). Just like there are some people here in America that would never buy a Volvo, just because it's a foreign car, there are some who will never buy a Mac because it's not made by Micro$loth/it's not what the majority owns/ it not ___________ (fill in the blank). Those folks don't know what they're missing.
As to the question of Micro$loth ever "eating" Apple, I hope never. To use the above analogy, my old Volvo is a much better made car than the current crop of Volvos. Why? Because guess who "owns" Volvo now? Ford!!! (The Micro$loth of auto makers in my opinion.)
