The Alleged Playstation Phone Looks … Good!
And so far, it's promising in its simplicity. Rather than gum up the works with Sony's Xperia operating system, the phone is running stock Android, supposedly version 2.3. Playstation games are accessed through a Playstation app.
Hopefully, it stays this way. I don't think Sony needs to heavily modify Android to make a good gaming phone, as long as the games are easily accessible and on par with Sony's PSP handheld. Like the Xbox Live app on Windows Phone 7, a standalone app could help act as a unifying hub for the Playstation Network.
Indeed, if the finished product isn't much different than what's shown here - and if there is a finished product in the first place - the biggest question is whether the games will be actual PSP titles. And don't forget that a PSP2 is rumored to be in the works; ideally Sony is working on a single platform for all its handheld gaming devices.
One other observation: This Playstation Phone has shoulder buttons, so it's got every input that the current PSP offers, and then some. (Note how the touch pads could act as two analog inputs instead of one.)
