All in all, it seems quite obvious that the iPhone has a strong advance in terms of sensitivity (light touch) while the HTC and Nexus One (HTC apparently designed this phone for Google) are quite good if you accept to press a little more.

So, Apple is not only marketing the iPhone through the roof; They also have a very good product and this explains (in part, at least) that the customers are so happy with the man-machine interface.
