The need of G-Wave

I have been using internet (read emails) for more than eight-nine years now. And except for some minor addition/improvements in some features, here and there, I havent seen much change in the whole format. So I am bored now. And who has the answer, who it can be but -- Google. Below are two videos and I am sure, they are the future. Have a look.

So what is it?

But the sad part of the story is-- it initially opens on invitation basis. The worst part is, I dont have. But if someone needs it, here is the last resort. Fill this form and wait for google team to respond :(
