Some of you may already be familiar with Orb, its been around for a few years now and works the BlackBerry phones with somewhat mixed results. Orb is an application for your Mac or Windows based computer and allows you to stream your media to web enabled devices (like the PlayBook) over the internet. So no matter where you are as long as your PlayBook has a connection to the internet your media is just at your finger tips. Best of all, it's free!
The first step is to download Orb to your computer. The setup is simple and straight forward, but if you get stuck they have some guides here to help. After you get Orb installed on your computer check out the video above to get up and running on your PlayBook.
