What application do you use for instant messaging? I'm guessing iChat would be the most popular, this being a mac user forum, but I find iChat to be too fancy and with unnecessary features. The little bubbles and stuff on the IM windows just annoy me. I currently use Adium, and I like how simple it is. But I know there are other choices out there, like Proteus and Fire that I haven't tried yet. How good are those other apps? Since I only use AIM, I don't need something that connects to MSN and IRC, so I haven't tried those.
