I was hoping for something like ChromiumOS. I'm not sure what's the point the author is trying to make here.
I am still waiting for a Ubuntu Spin that attempts to do this. It would make for a nice change.

You made me curious: what does mean _this_ in your comment? What do you like in ChromiumOS and would like to see in Ubuntu? What is in Ubuntu that you would like to have replaced with a ChromiumOS-like alternative?
Possibly some lightweight custom DE based on Gnome's SDK, like tiling manager possibly, to give it a ChromiumOS vibe, but you can still use other utils from Ubuntu. But one that's not too focused on shortcuts only.
PaperWM[0] is an example of a tiled scrolling (window) manager based on GNOME SDK (Mutter) that runs in GNOME session.
