You are right with many points: Chromebooks are indeed designed to be dumb terminals to Google's services. But on the other hand they have an amazing sandboxing system for all OS components and take security seriously. Compare this to most Linux distros that allow basically every local app full access to the user's account. I wouldn't use Chrome OS as it is right now. But a degoogled version of it, maybe with some better local only support, or at least support to use a different cloud than Google's cloud, say some NAS in my home, and it would be a really nice device.
