Sony Ericsson Xperia PlayStation Games
The Sony Ericcson Xperia Play is a mobile device that has just been released, and people are already unofficially calling it the PlayStation Phone. It combines gaming controls that are taken directly from PSPgo with Android 2.3 Gingerbread to create an attractive package. The PlayStation games are impressive, with titles like Bruce Lee Dragon Master and Gun Bros, even if the early build software does cause them to appear a bit awkward at times.
A bigger question is how will this compete with the upcoming arrival of the PlayStation Suite Android games store. Playstation Suite will be hardware neutral, so you should be able to get it on any Android device. There fore, if you want to play PSP titles, you don't need a dedicated device like the Xperia Play to do that anymore.
