We love the idea of Android apps running on iPhone and vice versa, and that's exactly what Adobe's selling with its multiplatform development solution AIR -- but though we've seen a demo here and there, conversations we've had with the company led us to believe that AIR was not yet up to the task. However, Adobe dev Christian Cantrell has the proof -- he created a game of Reversi that runs on five platforms without having to change a single line of code. In a video after the break, he demonstrates iReverse running on OS X, Windows 7, Ubuntu Linux, the iPhone, a Droid and the new iPad, explaining how it took only a series of seriously tiny platform-specific wrappers to make his program function on each. Since each platform has its own hardware strengths, this kind of convergence isn't always a good thing -- but if it provides extra incentive for developers to get cracking on hot new apps, we're all for it.
