Its nice to see some decent Android ports coming to PlayBook OS 2.0. The latest brought to my attention is All In One Remote by Hisham Hassan Bakr. He ported the media controlling app that works for Windows, Mac, and even Linux to the PlayBook and works over Wi-Fi and supposedly Bluetooth too. It offers you a touchscreen mouse to control your PC and keyboard along with things like a gamepad and other perks. It is not the most refined app and it is a port but it is also free which is a nice break!
Check out All In One Remote free in App World. You will also need the server app which you can download here.
