Macworld reports that Trillian is heading to the Mac, after being doomed to a Windows existence for many years. I'm not sure how welcome it is since Adium already fills that role (multi-protocol chat client) for OS X, but if it can give Adium a little competition, all the better.
It's still in the early stage of development, but I'll give it a spin when it comes out, and let you know whether it's worth a download.
