So, it looks like Google are going to be joining Apple and Microsoft by putting their digital assistant on their desktop OS. For some reason they are going to be adding a dedicated button on Chromebooks to access it (why can't they just access it with a long press on the search key or the 'o' menu thingy? It is accessed with a long press on the home button on Android; surely there's a case for consistency across devices, especially when Chromebooks are increasingly usable in tablet mode and that 'o' button becomes much more like Android's home button).
