I think the obviousness argument is getting a little confused in most comments about this case.
I am arguing that the technology itself was obvious. This is also what the OP is arguing. Several examples of prior art for patented technologies such as pinch to zoom, rounded corner rectangles, etc. have been presented in other articles here and elsewhere.
What is not obvious was the sum of each tiny part that Apple put into the design of the iPhone was commercially viable in such a spectacular way.
My understanding (though admittedly, I have not been following this case as much as some others) is that Apple is asserting several individual patents in the one lawsuit against Samsung. I argue that for the most part, each of these patents are "obvious". Sure, when putting all of them together into a single product, Apple made a successful device. However, weren't they just asserting several individual patents? I'm not sure they have a patent on "all of their working patents together in one device".
In addition, it is often the case that several groundbreaking inventions/ideas in science are not just spontaneously invented. Rather, they are the cumulative (and perhaps inevitable) result of small steps in other areas. For example, the invention of Calculus by both Newton and Leibniz, or the theory of evolution by Darwin and Wallace.
Yes, there are ideas which are truly revolutionary, but I'd argue that the iPhone was more the inevitable (I use the term very loosely) outcome of several small steps in related areas of technology.
EDIT:
This is why I am so against the patenting of human genes. Sure, some companies have put billions of dollars into researching specific genes. But why should they get a monopoly on that gene, whereas every scientist who put work into sequencing DNA, cracking the genetic code, understanding hereditary, evolution, scientific thinking in general, and anybody before, gets nothing from it?
It feels a little like they are doing an economic version of a Steven Bradbury[0], because they raced to patent the "inevitable/obvious" solution first.
Apple refuses to admit that they got where they are (i.e. iPhone/iPad/iPod by "standing on the shoulders of giants" [1]
