About 2 weeks ago, BGR broke the rumor of RIM's upcoming tablet, the BlackBerry PlayBook, possibly being capable of running Android apps sometime after launch, which the latest rumors put at the end of March/beginning of April with a price sticker of $499.99. The company was seriously looking into this possibility and was trying to decide whether using the Dalvik virtual machine (the same one Android uses to run its apps) was a viable way to move forward.
Zurich-based mobile software developer Myriad Group has announced the launch of "Alien Dalvik", an emulator which will enable unmodified Android apps to run on devices not using the Android OS.
App stores will be able to add Android apps to their repositories and they will be able to use Alien Dalvik to simply repackage the Android Package (APK) files for any device. Myriad promises that the repackaged Android app will run seamlessly and can be installed and uninstalled like any other native app.

Google has responded to Oracle’s suit, and they are ready to make a stand:
