Recall not very long time ago, like a year or two when google first announced its operation system "chrome os", people are full of doubt and questions that isn't it too early to put everything on the cloud? Cr48, a testing product of chrome os, is also full of bugs. I would say, it's the way that have to be, the world means to put everything on cloud, I just don't know when it would happen. But the leader in the field its google.
This is kind of revolution, as I mentioned, "what app" is dead in the water, in the full integrated world, you don't need an application to send or receive message, you don't need a mailbox. The same way happens to facebook, which tries very hard to become the entry of the internet, facebook wants people do everything in facebook, where in it people can share videos, games, text, applications, else.
But, imagine that, like what app, you don't need an entry. You don't need to open a page so you can share. when you open the browser, you are already on the net and already share something. Imagine your browser is the entry. Google makes it even further, no browser, your computer is your browser, when you open your computer, you are on the web, your computer itself serves like facebook. so what on earth we would need a facebook? obviously, if you are smart enough, you can continue to think in this way, in the future, we would not need a computer, because ourselves are the computers. in the end, what have left is you and your message, nothing between. (Now people communicate like you>computer>browser>website> receiver's website> receiver's browser> receiver's computer> receiver.)
