The iPhone is not a "finger responsive touch screen". These screens are really easy to make-- they have a grid of sense lines and can tell if there's a finger at the intersection of two of them. They are completely confused if two fingers touch the screen at the same time.

What the iPhone does is map the entire shape of a finger, as well as many other fingers, touching the screen to determine how many fingers, what orientation, etc.

This is completely different. That you and others claim they are the same shows the frank dishonesty at the core of the anti-innovation crowd here on hacker news. I'm at a loss for the motivation of anti-innovation people to hang out on an ostensibly startup oriented site, but you have succeeded in ruining it.
