The guys who make mobiPad have come out with a cool product demo video! I wrote about these guys a while back when I was judging for Mobile Content 2008. I can’t remember if I heard about them through the awards, or just at the same time. Either way, they should have been at the awards. I would have voted them right to the top.
Using mobiPad, you can control your entire mobile phone with the game controller of the Nintendo Wii. Use it to play games or as a remote control for the media player on your Symbian S60 or UIQ device (N95, P1i, P990) - the wireless gamepad is always an ergonomic way to interact. You can finally play standard games on touchscreen devices and no longer have to worry about buttons that are close together - and all this without buying a dedicated mobile games controller that you could not use for anything else!
