This video really gives great insight as to how many types of apps will be available for the BlackBerry PlayBook with very little if any customization to the code. Christophe Coenraets made a video tutorial showing an app ( Employee Directory application) running in an android environment then decided to download and install the BlackBerry PlayBook SDK and see how the application ran on the PlayBook using the emulator. Here is what he had to say.
“I was able to run the application without changing a line of code, with a great and consistent deployment experience.”
The PlayBook stuff starts in the video around the 3 minute 10 second range.
