Less so now that ChromeOS runs Android Apps and Linux in a VM. Both, unfortunately are heavily restricted to local storage so there's no real sense of being able to log into another Chromebook and have those ready and waiting for you. Android apps will reinstall but not always (read: almost never) with app data as before. Linux Apps is 100% manual still.

ChromeOS was great for 'switch to a new machine and log in' use... but it's so much more complex than that now. Only the most locked down managed devices wouldn't have to worry about anything left behind on a device before someone abandons it.

At this rate, short of a native package manager and repo for installing applications to run on ChromeOS (instead of a container Linux distro on top), ChromeOS might as well be considered a distro in of itself. Especially with CloudReady being installable on non-Google sanctioned hardware.
