Don’t unplug that USB!
It is true that sometimes users simply replay their own age old habits in situations like “Oooh! Don’t unplug that USB before unmounting! It might break”
It might be that the development team and testing already has taken care of it now that we are living 2017 and the habit simply re-lives in the minds of the users.
But to me it seems like a great opportunity for someone creating new products. If you can surprise the user by breaking their old illusions in a positive way, it will have an good impact on the future business too.
