Well, first of all, there is talk about a new system. And then again. It is going to based on a Linux core, so if one could / should
call it a new OS I'll leave to the reader. But for me, it is "just" another Distro of Linux. However, main thing here is, it is going to
be a Linux Distro with a major cooperation in the back for support. Not something Linux Distro's usually have.
But one thing readers have to pay close attention to, is this;
They want their data to be accessible to them wherever they are and not have to worry about losing their computer or forgetting to back up files
Those two lines, sounds like they are going to operate with the storage of the system in the cloud. Not a bad thing as such, but if that really is the case, how much space are Google willing to give, before you have to pay for additional space? Maybe they are going to operate most of the system in the cloud, and what you have physically in your home, is nothing but a Internet portal to Google OS.
Many interesting things to think about. But one thing I am almost certain of, is that it won't conquer the market. It doesn't sound like a OS for developers, programmers, industry etc. So I think that Apple and Microsoft will still have their share of the market.
But the sounding of trumpets for the next great war on the IT market is not a bad thing. The competition will force the players to step up to the plate and deliver better products, simply because more alternatives, means yours is going to be that more attractive to the clientel you want to use your OS.
So all in all, exiting new times ( might ) await ahead.
And seems the developement department in Denmark (Aarhus, Katrinebjerg) is looking for a programmer. I would almost say, that I am certain that it have to do with the new OS. And given the qualification requirements, it does sound like the Google OS is going to be clouded and with Virtual machine capabilities.
