Following a spate of leaks and rumors, the technology world is abuzz with talk of a 2-in-1 Google Chromebook tablet in the works known internally as ‘Nocturne’. We've also we’ve seen some pretty solid leaks that point to Nocturne being called the Google Pixel Slate. In the run up to its likely unveiling at the Google Pixel 3 launch event, it seems pretty likely that Google is working on a 2-in-1 tablet running Chrome OS. 

A leaked video has shown a possible Google-made tablet with a keyboard cover, while a more recently-leaked marketing image shows the purported tablet with a completely different-looking keyboard attached. Even renders of software updates showing preparations for biometric login on a Chrome tablet device have popped up. We’ve also seen speculation that the Google Pixel Slate will be able to dual boot into Windows 10 and Chrome OS.
