Hmm.
I agree, language changes. But just because most people will give plurals (god I'm shuddering just thinking about it) using apostrophes, does not mean it is right, or will be any time soon. Whoever "carry's" might abuse grammar, and "it's" abuse is still not correct.
Language does evolve, but it does not mean we have to put up with its degradation. There is a difference we can agree upon when it comes to "clip" and "magazine". It is a distinction that can be a handy one. By allowing the degradation of the word among ourselves, we lose the power of language that distinction once lent us.
Some people will say "wheels" when they mean "tires", but mechanics won't, because they're different things, and the distinction is helpful.
