I don't think new features are meant to be the attraction, at least not yet.

They seem to want it to become the next email, but for online messaging, voice, video, presence etc. To be an address on business cards. None of those things are new but marketing, a catchy name and a clean start will all help to get wide adoption beyond the tech types.

Necessary but not sufficient - some clean, rock solid clients as the face of it all are no less important... and so far they suck.
