Yes, back in 1989, when someone said, "Did you buy a PC or Mac?" all you would get was a quizzical stare, because no one would have had any idea what you were talking about.
I already said the word has gray areas. I would consider Commodores, Macs, Ataris, etc to be in that gray area. Relatively inflexible hardware, but flexible software. The PS3 was on the outer edge of that gray are for a little while. If you want to call them PCs, fine. But you know what? I can store software on my TI-86 calculator. I've had both games and scientific programs on it. Is it a "PC"?
You are still missing the point entirely. The Apple Macintosh was advertised as the Apple Macintosh Personal Computer. Notice the Personal Computer there? You are greatly confused.
At the time in the 80's everyone knew the Apple ][, Mac, C64, Commodore Vic 20, TRS-80, Amiga, Atari ST, and a whole host of other computers were "personal computers." Why? Because they were ALL advertised as Personal Computers.
What you are thinking of when referring to terminology is IBM PC compatible (
http://en.wikipedia.org/wiki/IBM_PC_compatible ). That was used to distinguish common x86 based PC's which were not built by IBM from all the other PCs.
The whole IBM and Compatible part were later dropped fromt that as IBM basically became a minor player in x86 PC manufacturing and all the other brands of Personal Computers died off except for the Macintosh which was rebranded as the Mac.
And you totally missed the other part of what I was saying. Let me bold it just to make sure you don't miss it again.
Your definition that I quoted. Specifically refers to a "closed system" versus an "open system" not as to whether they are a personal computer or not.
A personal computer does not and has NEVER had a requirement of being user upgradeable much less user upgradeable with non-OEM parts. As well while a "PC" is obviously a personal computer it's not usually used as such. As I pointed out above "PC" (as generally used) is an abbreviated form of IBM Compatible PC or IBM PC Compatible used to denote an x86 based personal computer and not generally used to denote "personal computer".
And here ends today's computer history lesson.
So yes, a PS2 running Linux (no hack required) can be considered a personal computer. A PS3 running Linux (again no hack required) can be considered a personal computer.
And to back that up, I believe some countries in the EU originally allowed the PS2/PS3 to be taxed as a personal computer rather than as an electronic gaming device. Heck I believe it was even Sony who likened the PS2 to a computer when they were launching it.
