For a long time Microsoft has been touting their ‘three screens and a cloud’ concept and here’s a picture of it in action today. Joel Ivory Johnson has a WP7 dev device and look what he did…so purdy. As he wrote “Bought a video on Zune and can now play it on my computer, my WP7, and my xbox 360″.” Yup, that’s awesome. Stepping back, getting a movie on a computer is easy. Windows Phone 7 is tied into Zune so that’s easy. Now to get it to your PC you have a bunch of options. You can use Xbox 360 or any other media extender device to stream to your tv. The other option is to wait a little while for the Intel system on a chip implantation of Silverlight to come to your tv which should be pretty soon and will presumably fill this gap as well. It really doesn’t matter how you do it – Seeing it on three screens is a treat.
