Here's my two cents.
First of all, back in the day, the Macintosh computer was outclassed as soon as the Atari ST hit the market. That (and the Mac) were outclassed by the Amiga when it came out. Yes, it's true; the Atari ST, for half the price of a Mac, was twice the computer.
Now, Apple did some very smart things. They contributed heavily to Postscript, giving them a very good foothold in the lucrative desktop publishing industry. Admittedly, the black and white graphical Macintosh of the day was an ideal computer for this single purpose.
The Apple Macintosh and Amiga were completely different machines. The Amiga could multitask; the Mac could not. The Amiga capitalized on video and sound, while the Mac focused on printed output. Most importantly, at least to me, the Amiga, while a different machine, tried to stick with industry standards; at least when it came to peripherals such as modems and printers.
To me, the modern PC is closer to the Amiga than the Macintosh is. Just like with an Amiga, you have a choice as to what peripherals you can use. With the Mac, there was no such choice until it became more like a PC. Also, just like PC's of today, the success of the Amiga platform came largely from user contributions.
Some facts:
Apple is a company. PC is an INDUSTRY made up of many different and competing companies.
I worked for Apple tech support years ago. They believed that Apple was superior then. Today, it's much the same; a lot of smoke and mirrors, a lot of reality distorting, and a WHOLE LOT of comparing rather expensive Macs to bargain basement PC's that cost a FRACTION of the price. They also seem to believe that Windows constitutes the entire PC industry; which it does not. There are PLENTY of OS choices for the PC platform. Always has been (OS/2, DR-DOS, etc), always will be (Linux, FreeBSD, etc).
My server is an AMD K62-450 that was a PC originally built in 1996. Since its architecture was open, I have been able to upgrade it through the years. It started as Pentium 120 with 16k of RAM. Today, it has over 200MB of RAM, a good sized hard drive, is Y2k compliant, and accepts modern hardware such as USB devices and runs a modern OS; Ubuntu Linux. Anyone who believes that modern PC's only have half the life of a modern Mac is obviously referring to a bargain basement PC, and not a PC of comparable value which will, in all likeliness, outlive the Mac.
Honestly, the Mac is a nice machine; often attractively styled, reasonably priced for the level of quality you get, and clearly has appeal to people who would rather own a computer that functions as an easy-to-use appliance. I would not fault someone for wanting to buy one. On the same token, to say that a Mac is somehow better than a PC without really quantifying what PC, or even making an accurate, educated comparison, is absurd.
