I haven't looked at all of the ChromeOS announcements yet but it would be nice if developers could write apps for ChromeOS using Flutter: not Android apps that can be deployed on ChromeOS, but ChromeOS-first apps. Ubuntu's developers have taken to Flutter as an ideal tool for writing desktop apps: as easy to write as a web app but without the memory and performance overhead of the DOM and JavaScript. Would be nice if such apps could be targeted specifically for ChromeOS.
I just updated Chrome OS on my Chrome Book and it totally whacked out my bluetooth mouse again. Lately (say last 8 months) it seems there's almost no QA before they push an update.
