Some software which allows multiplayer gaming between two or more similar devices (with Atom processor) via wifi or bluetooth or any other wireless connectivity. The game screen should be displayed on both the devices. That way man vs man combat playing and other games can be easily possible rather than playing with computer. A device with Atom processor is expected to have such small keypad multiplayer gaming is not possible on a single device unless two such devices are there where two keypads will be available for two players.
Hope its understandable. :)
