I don't know if anyone has made this observation re the evolution of the iPad vs the iPhone, but the iPad 2 went to a rounded back from the square, flat back of the iPad 1. The iPhone went in the opposite direction from the rounded back of the 3 generation to the flat back of the iPhone 4.
I'm not sure what it means except that some complained the older phone would not sit still for keying when sitting on a table while the curved iPad is easier to hold.
