While at the BlackBerry PlayBook launch event I confirmed that my favorite feature of the BlackBerry PlayBook Tablet managed to make it into the launch OS. The BlackBerry PlayBook has a feature called Storage and Sharing that I absolutely love. It allows you to access your BlackBerry PlayBook file system and storage over Wi-Fi from your PC with NO CABLES. I personally think that every device should have this feature but the BlackBerry PlayBook is the first non-Desktop device to have this feature. I have been using it all night and I absolutely LOVE IT! It is a bit slower than I would like (I am seeing about 100kbps) but in my opinion is one of the most innovative things RIM has done with the Tablet OS.
You simply setup a network name for your device along with a password and then mount it like any other network drive. When you mount it you are given three main directories: Certs, Media, and Print but all of them are empty except for Media which has all the subdirectories you see in the screenshots.
Let me know if you have any questions about the feature!
