If you are a Mac user and if you want an extra monitor that can turn your iPhones and iPads into external multitouch displays. Then what to do is download the iDisplay app, an extension for OS X, and let the data flow over either Wi-Fi or 3G.
Now, just turn your iPad/iPhone into a convenient side monitor for your Mac desktop. This is right that the connection goes both directions, so you can use your multitouch gadget as an input device. The iDisplay app is $4.99 and available in iTunes whereas the corresponding OS X extension is available through the iDisplay website.
Wow! great news, is not?
