Samsung haven't done that either, but they've created (some) products that look extremely similar to Apple products, in similar packaging, even going so far as to putApple icons and the icons of Apps exclusive to the iPhone in their marketing materials. Some of Samsung's Apple copying has been hilariously comical in it's ineptness.
If there is a line it's possible to cross, then I think in some products Samsung have crossed it. Not every product, not even all the ones Apple is citing, but some of them. To me this is nothing to do with patents, I and against software patents, it's about trade dress and brand confusion. I wish Apple had more narrowly focused their objections on those specific issues.
