Android apps on Windows? Been there, done that. Try running Windows programs on Android for size. Alexandre Julliard, the developer behind the Wine compatibility layer, gave an update about an ARM-friendly flavor of the software and showed off a version that runs on Android at the 2013 Free and Open source Software Developers' European Meeting. According to Phoronix, the demo of a Windows app running on Android was "horrendously slow," but Julliard chalks that up to the fact that the sample was chugging along on an Android emulator. Wine for Mountain View's OS is said to be an active work-in-progress, so there's no word on when it might find its way into the wild just yet.
