Hmmm...
Mobile phone gaming has steadily been increasing in popularity over the last few years.
And now, if you really dig playing games on your phone, you can even get a controller specific for mobile phones. It's called the Zeemote JS1. Although judging from the familar-sounding name you may think it is a motion-sensor controller, it is not. It's just a wireless controller that you control with your thumb.
He can see a video of it in action over here. The Zeemote is currently compatible with Heli Strike, Pub Darts 180, Sonic the Hedgehog, PyroSonix, and a few other games.
Could this be the first time in gaming that a controller has been almost as big as the console / platform?
