In the current war of OS's, we see a new OS every six month's interval, which is not very shocking either. We have seen some great team of developers, getting huge startups from big startup companies, and hence we are seeing more and more OS months after month. From MacOS to AndroidOS, the choice of OS is very large and never-ending.

We have seen some of it's earlier build images running on Nexus range of devices and some other top-notch devices though they weren't stable enough.
