Apple doesn't hold a patent on the touch screen tech.The iPhone's touch hardware is quite ahead of everything else - and I believe that a lot of it is patented as well. So no, I don't agree that all other phones have superior hardware. If they did, other phones wouldn't have such terrible touch screens compared to the iPhone.
The same type of touch screen is in several HTC devices and the Storm.
All of them use capacitance based touch screens.
Meaning fingernails or a stylus will not work on the screens.
