Here is the latest concept phone from Sony Ericsson. It offers multidimensional features in a single model. If the slide is moved down, you can see a keypad. If the slide is moved up, you can see the gaming keys. It also offers other standard features from Ericsson such as a 3.2 MP camera, a media player in it. The added advantage is that of a WiFi connectivity slot which helps you to browse at any place. The major disadvantage is the battery life. Since gaming requires more power from the source, a normal phone battery cannot withstand such power. Sony has to change the battery if its PSP concept phone has to find success in the market.
