Perhaps. It’s just a text editor, though, which I use for note-taking — I had been using Word (with the kinds of fancy auto-correct features that Meg mention), but I frankly got tired of my notes files becoming so weighty because Word was freighting them with a lot of unnecessary data, when all I wanted was the content. (Which is to say, I didn’t need formatting, page layout, etc; all I needed was the text.) My text-only notes files are much, much lighter weight, much more easily transportable, etc. But they’re just text — there’s little to no formatting involved in them. If your husband is looking for a program to take notes in, something like TextMate might be good, but it can’t, unfortunately, replace a full-fledged wordprocessor…
