Earlier this week, Trillian, one of the oldest third-party IM client developers, released its Android app. I've always found Trillian a bit gimicky -- kind of like a 'Super Mega' Windows Live Messenger, with more bells and whistles than I really need, and a bloated, hard-to-navigate UI as a result.
Trillian for Android, I'm sad to say, is no better. Ultimately, it's functional but it feels like the shedding of its beta moniker was more than a little hasty. If that wasn't bad enough, it'll cost you $5 from the Android Market.
