We knew it was coming, but today at BlackBerry World 2011 we were treated to a demo of Android apps running natively on the PlayBook. The end result isn’t too far removed from what we saw with Myriad’s Alien Dalvik at Mobile World Congress. Android’s menu and home buttons are emulated using the standard PlayBook gestures, and the back button is replaced with an on-screen softkey. Of course, you’ll have to visit App World to download Android apps for the PlayBook when the Android Player (as it’s called) finally becomes available. And speaking of Android apps, the wildly popular Angry Birds is coming to the PlayBook as a native game – no cross-platform trickery required.
