I am pretty sure that it will always update, from now until eternity. I mean Chrome OS is a real PC OS. Just like Windows still updates, I see no reason that the Chromebook would stop.
I think the question is whether a current model Chromebook will stop being updated the way older Android phones stop getting the most recent versions of Android? If so then so far Google is saying no, it will be different in that ChromeOS will always be updated, and won't hit hardware limitations that would cause you to have to get a new Chromebook to be updated.Does anyone know how the chomebook updates will work? Will it be like Android where at some point it will not be updated anymore or will it continue for a long time?
