I find it quite encouraging to see this really. I think one of the flaws of mobile gaming on things like the iPhone is that the touchscreen is a really terrible way of interacting with many control schemes, both because of the lack of tactile response and the fact that your fingers invariably get in the way of the UI.

The fact that it's running Android is a big plus considering Sony's penchant for running with their own tech (either hardware or software) and either noone else adopting it or discouraging from others adopting it.
