You realise that every single school/education department that chose to use Chromebooks did so knowing that they would not run anything but web apps, right?

Additionally, this announcement of a future release lists very specific models of Chromebooks that will support Android apps. Honestly, Android (and Google's management of the situation) has a fucking terrible track record when it comes to support and updates for devices.

Lastly - if you think that apps designed to run on a smartphone and later frankenstein'd onto a low cost laptop form-factor with a browser-as-the-os tagline, I think you should prepare to be surprised.
