I see your point. My counter-argument would be that it solved a unique touch-screen problem of a lack of keyboard/mouse and a lack of an easy way to highlight text.
I think the thing I'm hung up on is that Apple stormed into the phone market and did a whole bunch of smart things that nobody had thought of, but are obvious in retrospect.
I don't agree with software patents, but I can't help but hesitate before agreeing that it's beneficial to the industry to let Apple's competitors wholesale copy their work (even the small things).
