Nope, that's not all that should matter. The reason is copyright vs. patents. Both are made to prevent copying but in different ways. Copyright says this product is not copyable. Patents say this aspect of the product is not copyable. HUGE difference. Now in this case Apple used several patents to act similarly to a copyright. The difference is that these patents were found valid meaning that if your product infringes even ONE of them, you can get sued big time. So if you create a product with rounded corners you could get sued, even if you didn't copy apple at all. Should Samsung get sued and pay $1 billion for copying Apple? Probably. Should Samsung get sued using individual aspects like having rounded corners? Definitely not, considering now several companies who have done nothing wrong will be liable.
