I agree with DiapDealer. I
want physical keys. Yes, I know how to use an all touchscreen interface, and I am very "familiar" with it (I am forced to be by the industry), but but I don't like it. They can add a touchscreen to my physical keyboard. My detailed thoughts on Touch are in a comment to this post

"Loss of function" is not the only criterion for assessing an interface. Usability, speed of operation, preferences of large groups of users are a few others. After iPhone, the wants of DiapDealer, me and other similarly minded people are ignored.
