Actually, the "Personal" in PC is kind of redundant anyway, a hold over from when you had to make a distinction that someone's computer was indeed "personal", and not a server/timeshare/mainframe of some sort.
Now it's the opposite, you say "Computer", and you have to make the distinction if it's some sort of centralized enterprise class machine.
At least "Computer" itself is probably not going to go away, because even if the end-result meta-output for the end user is not mathematical or numeric per-se, there was a hell of a lot of computation involved in displaying it still, be it fonts, graphics, sound or video.
So count me as "does not matter" in the pistol vs. revolver debate.
Yes, revolvers are pistols, in terms of being a firearm designed to be used by one hand, either derived from the Italian gunmakers of the town of Pistoia, or possibly from the word pistala, of the Hussites for their one handed short cavalry firearms from what is now the Czech Republic region However, it's a common appellation to use "pistol" to talk about single shots or automatics that do not revolve as well. Possibly common enough it's now "official", in terms of dictionaries or whatnot.
I think there's definitely more leeway between pistol/revolver than there is magazine/clip.
