Right above the keyboard
Intel demoed a new prototype notebook they have been working on, code-named Tangent Bay (cool code-name Intel). The most eye catching feature the notebook displayed was four displays: beside your normal everyday display, there are three little OLED screens situated above the keyboard.
The design concept was ballyhooed as the Earth's first multitouch and multiscreen notebook.
The OLED screens are fully functional mini-displays: users can set them up however they see fit. Just by using your fingers -- or whatever else you would like to use, such as your toes for example --- you can drag content around, screen from screen. It is easy to imagine this feature actually being fairly useful.
You might, for example, have some Youtube videos playing on one of the OLED screens for entertainment while you are supposed to be writing an essay; or, you could have some open IRC chat windows going on one of the OLED screens, while you are suppose to be doing tech support for someone.

Hee Hee, I do it sometimes, but not on the OLED screen yet, for instance, I used to open and listen some Youtube music videos while I'm writing an academic essay, I mean just to get some fresh academic ideas out of nice musics!!!
All in all, OLED displays are awesome in every possible way, I suppose.
I imagine there are many productive uses possible with the three extra OLED screens -- but there are probably man more unproductive uses possible
