Trillian just released a new version of their software. If you follow the link, you'll see that it's an IM client that works with all of the major IM vendors (AOL, MSN, Yahoo, etc.). The new version definitely
feels slicker and faster. I also love that they insert wikipedia links right into the text. I may get annoyed with that later, but right now, that's awfully cool.
I used Trillian .74 off and on for a while, so with the release of version 3.0, I decided it was time to use it full-time and get the Pro version. $25 is rather cheap for the utility it provides. And yes, I looked at GAIM before, but I just wasn't impressed.
