The only reason I mentioned it is because OP's usage caught me off guard. Most of the time in colloquial usage I've seen PC used as an acronym to mean "computer with Windows installed as the OS", especially when being compared to Apple's products.
But in this case it was used as "desktop computer", which sounded strange to me as I consider laptops, however portable, to be personal computers.
I agree with all of that -- and regret the recent trend of using "PC" to mean desktop as opposed to laptop -- but what does any of that have to do with Apple's marketing?
You don't think Apple's marketing is behind the aforementioned recent trend; do you?
My understanding was that Apple's marketing created the initial deviation from the original meaning which led to the current one, but yes seeing what other people are commenting now it's not that simple and I was wrong on my assumption
