Take the latest iterations of the Play store for instance. A while back they introduced a semi-floating search bar on the front view, that has the "hamburger" button integrated. Except that if you put a tablet into landscape, that bare stays fixed width, so now the burger button is suddenly not in the top right corner.

And i think Hangouts produce a single column down the middle with massive whitespaces on either side.

Edit: Thinking about it i wonder if this device is Google's attempt at dogfooding tablet development. Right now it seems that most of their apps are developed firstly for Apple devices.
