George Kokkinidis made this collection of shots of iPad displays after being used with different applications.

It reminds me of the eye tracking techniques that analyses the flow of our visual attention when looking at pictures, text, websites etc.

If Microsoft gets this to the market before Apple comes up with a big OSXmobile device then they have officially won me back!
