OT, but to push even farther OT, how do you propose to designate a "non-Apple" PC? Used to be able to use the term WINTEL (never mind that WINTEL has another, unrelated meaning
). But now that there are plenty of machines built around non-Intel CPUs, WINTEL isn't such a good fit. And, since Apple has about 15% of the personal computer market, "non-Apple" is a little like calling a hamburger a "non-soyburger."
Fact is, there was originally a product called the "IBM PC" and the "PC" name just stuck, like kleenex, bandaid, sharpie, bendix, and many other product names that became common names. While it may not be technically precise, when I ask someone if they have "a PC or a Mac", the vast majority know exactly what I have asked. Common usage tends to prevail.
