The Nexus 7 when shown at Google I/O looked a bit odd, It looked like it was stuck in phone mode as well as portrait mode.
Turns out portrait mode is to blame as the launcher and needs a slight tweak. Phone mode on the other hand is down to the screen and its DPI. Just tweaking the Nexus 7’s build.prop to a DPI of 170 will make the tablet UI that looks oh so good kick in.
As you can see in the screenshot it looks 100 times better instantly in my opinion. The switches have changed from the parallelogram (god that hard to say) styled switch to a normal rectangle that looks like Apple iOS switches (as im sure they would argue it in a courtroom.)
