Really?
Because I'd use a shoe as a doorstop.
I'd never "utilize" anything.
Update: Well, on doing a bit of research in to this instead of just using my intuition, I found that you're absolutely right about the special meaning of the word "utilize", according to a number of sources like [1].
I guess I must have been too hard on those people who were properly using the word.
Still, a survey of articles on these terms shows I'm far from the only one for whom the word "utilize" sounds pretentious, so in ordinary, non-specialist language I'd still err on the side of caution and use the word "use", which can in fact be used correctly everywhere "utilize" is used.
There's a good discussion of various points of view on this issue in [2].

It's a pet peeve as well, but they don't mean the exact same thing; you "use" a doorstop to hold a door open, you "utilize" a shoe as a doorstop. "util - ize", to turn something into a utility, in a way that it wasn't before. Use an umbrella, utilize a leaf as an umbrella. Use email, utilize email as file transfer system.
