Apple designer Susan Kare actually testified that when she was playing with the Samsung phone, she swore it was an Apple iPhone! Her testimony was quite convincing. It convinced millions of people that for a lot less money, they can get an iPhone by buying Samsung's phone. Genius!
....This is a disaster for Apple no matter what Samsung does to its interface and its rounded corners. The case and its results, because of Apple testimonies, make it sound as if Apple was suing because a better product evolved.
