>But Android OS doesn't resemble an iPaq, it resembles iOS.

Both have significant similarity to a year 2000 iPaq. Full screen mobile device using a touchscreen against an icon grid, onscreen keyboard, etc. The iPaq was a "PDA", however, which somehow differentiates it. I owned one. I know how they are similar.

>You keep inferring that everything presented in the original iPhone was an obvious extension of what we'd seen before, but it simply wasn't.

No, I'm not inferring that whatsoever. I am arguing whether its uniqueness is patentable. We've seen with various iterations of iOS that it is borrowing from its competitors as well. That's how the world works.
