In the last 10 days or so Trillian Pro 2.0 and Helium 1.7.1 were released. Essential software in both cases. Trillian’s meta contacts are useful, while Helium’s album cover management is quite cool. As to Skype, no I didn’t try it yet (last week was spent struggling with, then making tons of phone calls with Vonage) but I’m about to, as I’ve recurring problems with voice support under MSN Messenger.
