It's almost a crap-ware. Doesn't look good. Is of no use, being iOnly.

FaceTime is a good app but being iOnly this one is pointless too. I am looking for a desktop alternative other than Skype.

Viber is a thousand times better, with it's desktop and extremely famous mobile clients. Wish other truly messaging apps like this and WhatsApp would go desktop too.

PS. Google gonna support hangout on others clients like Adium after full transition?
