What DOES the term PC imply? I don't mean to try to get at a sensible a priori definition of "PC" - I'm aware that as far as the world is concerned they're just branding terms used by Apple. But where the delineation is obvious when we're considering nothing except Windows and Mac OS, it gets greyer when we consider Linux, BSD and so on. Could I have some hardware custom built, and write my own operating system for it, and call it a personal computer that's not a PC, or does only Apple have that power?
I don't think anybody referred to Acorn Computers as PCs (so, no, not only Apple).
PC means different things according to the context, but the main ones are
a) IBM-compatible PC. Which means Windows/MS-DOS.
b) Personal computer, which means Mac
The 'I'm a PC' advertising campaign, while quite entertaining, seems a bit outdated now IMO. Probably because compatibility issues aren't much of a headache these days for Mac/PC owners, who primarily just go on Facebook and check their email. Seems weird that Windows users would still think of themselves as 'PC' people.
