Pros: Delicious multi-way A/V conferring system; fun image manipulation tricks; very stable.

Cons: No extras available; you're stuck with one of two contact list themes.

Review: Well, it comes with the Mac so chances are you've booted it and played silly buggers with it's image manipulation tomfoolery. As far as A/V goes this is nigh on untouchable - it's smooth, fluent and hi-res. As for the interface, well, you could do better but it's not all that bad to tell the truth. Group chats in A/V are a joy to behold and multiple text chats open up a nice little drawer a la Proteus, saving the need for multiple open windows. If you're interfacing with other Mac users, this is THE app to use, full stop.
