Has anyone patented rounded corners yet? If not, I see an opportunity

From Matt Yglesias via Alex Tabarrok:

…Apple has been awarded a patent on wedge-shaped computers. Once again it is difficult to see why this sort of competition-stifling government-enforced monopoly would be beneficial to the overall cause of innovation. It’s absolutely true that the record should reflect the fact that Apple made wedge-shaped computers popular and the new wave of Ultrabooks are slightly lame imitators. But we progress as a society because of imitators! People come up with good ideas and then those ideas spread.
