If the Samsung 2263DX 22-inch LCD is Dr. Evil, the small 7-inch LCD grafted onto it would definitely be Mini Me. The idea is that the main 22-inch screen can be used for normal work and the secondary 7-inch screen can be used to extend your desktop to keep other stuff visible.
I guess you could use the little screen for IM applications, RSS feeds, and TV watching or other things. The 7-inch screen attaches to the main display via an arm that allows it to be mounted to either side of the main display or above it. The small display connects to the main display via a mini USB cable so you don’t need to directly connect the small screen to your computer.
