Chromebooks have the advantage of keeping state in the cloud. The other day I started editing a document at the office on my desktop and finished it on the train back home. No need to even think where the document was - it's always available no matter the device I'm on.

Office 365 is kind of the same, I know. We can think of these machines as Office 365 clients just as much as we can think of Chromebooks as Google clients.

But, at least for Chromebooks, you can seamlessly add a fully functional Linux environment.
