Pros: Active development, very attractive interface, Twitter integration, Facebook integration, drawer keeps multiple chats in one window, multiple live avatar choices including Photobooth style morphing.

Cons: Still no AV.

Review: A very attractive little client, well endowed and advanced. An excellent client to choose if one is forced to choose, especially since a huge amount of people use it as a protocol.
