Bravia Engine with Reality Display. There's a 1GHz processor inside, access to Android Market, and home screen customization with custom shortcuts available in the four corners of the screen. A 30 percent improvement in battery life is also touted, courtesy of a larger cell. SE is also pretty jolly about having the world's smallest smartphone capable of recording video in 720p HD. You'll be able to grab yours in one of four different colors this August.
The new Xperia Mini Pro features the same 1GHz processor, 3-inch display, and 1200mAh battery, but it also adds a front-facing camera and that sliding QWERTY keyboard that made the original X10 Mini Pro such a favorite. The new model is coming at some point in the third quarter of this year. Sony Ericsson's launch presentation is still ongoing, but we'll have more details and hands-on pics as soon as we can.
Update: Hands-on pics and impressions can be found right here!
