I’m still very happy with Trillian, so much so that I’ve upgraded to Trillian Pro. With the Pro version you can use plugins, and I’ve installed a very handy GMail plugin. Now in addition to handling all of my instant messaging, Trillian also checks my Hotmail, Yahoo and GMail accounts so I don’t have to waste time logging in to check for new messages. I still need to check out the IRC functionality, which would just be icing on the cake if it meets my needs.
