You make it sound as if Apple PCs are beyond comparison, a class of their own. Which they aren't. I am not saying they are not good (another discussion), but I don't see the supposed revolutionary part.
The amount of time people have to waste on PCs waiting for the OS, doing anti virus stuff, staring at blue screens of death, rebooting because it's got confused, etc etc
But this isn't an OS war thread :) Suffice to say, "It's still just a PC" is completely missing the point. A top class restaurant still 'just' serves food, but you can't really compare it to Macdonalds.
And to many people, Apple are in a class of their own. If I didn't currently use a macbook, I'm not really sure what else I would use. Some of the Asus laptops look ok enough (At least like cheap copies of Apple design), and maybe Ubuntu is getting mature enough on the desktop to be useful, but there's not an obvious alternative.
Regarding "I don't see the revolutionary part", you don't have to be revolutionary to be better than everything else. People use Apple stuff because it works and is well thought out. It stays out of their way and lets them achieve what they want to. It's designed to make everything as seamless and useful for the user as is possible.
Some people just want a car to get them from A to B. So they buy a standard boring crappy Ford or something that looks like a dog. As long as it gets them from A to B, they're ok. Others actually love the 'driving' bit, and enjoy it, as well as having a thing of beauty. So they buy a better car. Same is true with computers (And most other things).
Just saying, the "easier to use, no rebooting, no blue screens of deaths" are a complete marketing fabrication. Except that on OS X the death screens are not blue.
Edit: as for your edited part - I am not saying Apple PCs are bad (holding my opinion back), but the article made it out as if they are revolutionary. That is what I am arguing against.
My personal experience:
Windows/dos user for 10 years Linux user for the next 10 years OSX for last 3 years or so
From my experience, the last 3 years has been my most productive, and I've spent far far far far less time messing about doing unuseful things (Trying to get wifi working, trying to work around OS issues etc).
Don't just dismiss everything as 'fanboyism', I used to do that 10 years ago. I thought Mac users were rich pretentious egotistical people who didn't actually know anything about computers.
Also, it is not really fair to compare Apple to all the other PC vendors out there. Some of them probably produce crappy machines, but others don't.
One of the key things that puts Apple in a different class though is that they create the hardware AND the software. That's a big bonus and gets rid of a ton of potential hickups.
I didn't even imply that Macs are better. Although I do think that Apple controlling the hardware and software has allowed them a lot more time to focus on the software than the bureaucracy Microsoft has to deal with to help software publishers and PC manufacturers. There is a lot of stuff I can only do on Windows and that in itself is important to note.
