One great feature of iOS 5 is it brings more excitements to gameplay. With the iOS 5 on your iPad 2, you can use it as a wireless game controller over AirPlay for playing games on an HDTV that has an Apple TV connected.
The Real Racing 2 HD title will be the first few that will support wireless AirPlay gaming, letting you use your iPad 2 as a wireless game controller to play games on the big screen.
Similarly, the recently announced Wii U by Nintendo at E3 also offers itself as a 6.2-inch single touchscreen controller that allows you to use it a wireless game controller for playing games on a big screen. Check out the clip below showing how Wii U is used to wirelessly play Zelda in HD on an HDTV.
The Wii U costs somewhere around $250 USD and it’s solely driven by the Nintendo game console that it connects to. Whereas, the iPad 2 is a standalone device that’s useful for many things in life. So, if you already own an iPad 2, what you need is just an Apple TV that costs around $100 to setup the equivalent. And getting a pair of the Fling Joystick should bring the iPad 2 closer to Wii U; having button and joystick kind of controls.
