Should I prefer iterators over const_iterators?

Question

Someone here recently brought up the article from Scott Meyers that says:

• Prefer iterators over const_iterators (pdf link).

Answer 1

By my reading of that link, Meyers appears to be fundamentally saying that interator's are better than const_interator's because you cannot make changes via a const_iterator.

But if that is what he is saying then Meyers is in fact wrong. This is precisely why const_iterator's are better than iterator's when that is what you want to express.
