How does the XDK differ from the Public (Retail) Xbox 360?
Besides the XDK debug software, the actual unit itself is gray in color instead of the trademarked “Chill” white. The additional software in the XDK gives you the ability to take screenshots of games through your computer network. The console also sports a larger hard drive as opposed to the standard 20gb hard drive on the retail unit. You can also play game titles from any region around the globe.
