I found it interesting that he mused about the 3.5" vs. 4.12" screen, particularly when you take into consideration how Apple has defended their designs recently. If it is really true that they hit on the "this is the size that humans perceive as perfect" goldmine, then the way that Apple has argued against imitators is less "they shouldn't copy" and more "we want to be the only ones who sell 'perfect'". A subtle difference, but if true, a very interesting approach to battle your competition. After all, it leaves you in a very comfortable position - your competitors can try all day to build strong products if you have control over the ultimate perfection that nobody will be allowed to get to. At least for now, you can't patent sizes, but it's not like we haven't said this about other things and it's certainly not like they wouldn't try.
