I recently updated my Google Account password. The Chromebook had to do a migration of my profile. All went fine. However I think the UX during the migration could use a bit of touch up.
Requires old Password
I imagine this may be because the data is encrypted using the the Google Account password. My concern being, what if the user forgot their old password which is the reason for changing their password? I would have to hear some thoughts for and against this, but what if a unique key were created and stored server-side for any encryption? That might cause issues for an offline login to the Chromebook. I would have to think about this
The migration takes a little bit of time. During the process there is a no UI message, the Chromebook acts as if it were froze. Either a please wait message or the built in spinning loading mouse cursor would be good feedback for the user.
Overall the Chromebook is fantastic. I love the CR-48 and it continues to run the latest version of Chrome OS well!
