It depends what you're used to, and what you're doing. If you're mostly just typing in some text, not doing a lot of editing, such as for a short comment like this one with only a couple of tags, you can get by with a textarea okay. Basically, whatever you could do in a very basic text editor (a la Notepad) you can do in a textarea. Obviously, for anything more complex, you want a real editor -- by which, obviously, I mean Emacs ;-)
