I had a chance to play around with it and these are my thoughts: It's definitely pretty. The animations are fairly smooth on the Series 5, which is surprising because the Atom processor chokes on a lot of big websites. Unfortunately I don't think this greatly helps your productivity while using Chrome OS. It's more convenient for having multiple windows. Perhaps if you were doing some writing in Google Docs you could have 1 window for your writing and research, then another for when you want to take a break. That makes sense. However it seems, and I could be wrong on this, that when you open a new app it opens in a tab within whatever window you were last using. It feels like something that was designed purely as a "how do we abstract away windows management" and not about usability. They need to do something to make apps be real apps, meaning no tab chrome at all. And they need to intelligently find a way to do that. So perhaps apps launched from the home screen will default to launching in a new window without any chrome, and they would need a good way for multitasking from there (the auto-hide bar is a fair start).
