"Personal Computers'", "Micro Computers", "Home Computers" - are all nebulous terms.
That makes absolutely no sense.
At one point x86 was part of the "Personal Computer" criteria, then it became anything that would interpret x86 (AMD-64).
Right. I guess you didn't call a 286 a PC? How about a 386 computer?
The step of 80286 to 80386 was much larger than the step to AMD64, but do you refer to a 80386 as "anything that would interpret x86"? Given the rest of the post I guess "yes".
Now ARM devices are "Personal Computers".
... I guess your phone is one too then?
Semantic pedantics enjoy pointless arguments have no point of any importance to make.
If a PC runs business software is it still a PC?
Of course. PC doesn't necessarily mean one uses it only for personal tasks.
If you put it on the floor is a desktop? Did you see those pictures of Lady Gaga? (sigh). Oh, and you're grammer is wrong. (I was going to work the word "nowadays", and the phrase "moving forwards", but...)
You are a confused individual. Try not to waste my time the next time, some thinking before writing makes a huge difference.
