I wonder if Sony can block pad use if they want, based on the switch process of opening the pad? Here is a snip from Cnet UK: For instance, sliding out the game pad launches the 'Xperia Play' app, which is divided into 'Xperia Play Games' and 'More Games' sections. It's not exactly clear, but the former section hosts games that are already installed, and the latter section takes you to a sliding menu of titles that you can download. Tapping on titles in this menu enables you to buy them, and here the first problem becomes clear -- there's no single store from which to download games. Seems if Sony wants to force folks to buy their optimized versions, they could easily block folks from using the pad for any app not Sony spec optimized.
