It's sometimes handy to have an apostrophe (correctly used) to indicate some state of affairs with precision.
It irks me to see it misused; one of my correspondents uses it for almost everything and he's educated enough to know better.
The irk factor isn't as intense as seeing a finger on the trigger unnecessarily, or a magazine with cartridges loaded backwards, or calling a cartridge a bullet, but it's there, if you see what I mean.
On the other hand, one apostrophe rule I hate is the one about its being its own possessive and not needing an apostrophe. I don't know how that came about, but I don't know how "GH" came to be pronounced "F," either.
As an example, compare:
"The car's engine was running." (correct)
to
"Its engine was running." (correct)
whereas "It's engine is running" is incorrect.
Go figure.
I'm not sure how many languages don't use an apostrophe our way, though.
