People who keep saying PC when they mean a Windows or Linux machine. As if the Apple machines weren't PCs too.

(Lenovo's mentioned because they bought IBM's PC division.)
I remember being hugely confused by this when I first saw a PC, asked my friend what kind of computer it was, and got the answer "it's a PC". Like being told "it's a computer". Thanks?

Here also is an article about desktop publishing from 1990.

It talks about "running a Mac-based system and a PC-based system side by side", and how "some text and graphics files can be moved relatively easily between Mac and PC formats". Opposite is an advert for Toshiba's early IBM PC compatible laptops, bragging about winning awards from PC User magazine, which I don't think featured Macs.
But when was any Mac ever called a PC? I don't think the Mac Plus, for instance, was called a PC at any point?
SoftWindows was Windows bundled with x86 emulator https://en.wikipedia.org/wiki/SoftPC, created in 1986. Note the PC in the name, apparently equivalent in meaning to x86 already. Maybe this was implicitly short for IBM PC Compatible, maybe the term PC was ambiguous back then, and for the next two decades, but I doubt it. (Clearly it is still somewhat ambiguous, though, or I'd have nothing to wrangle about here.)
And it was specific to the PC model. The PC was a new architecture and IBM was otherwise better known for their other products at the time.
PC was established long before those Apple commercials.
