You hands moving from the keyboard to the screen is probably farther than your hands moving from a keyboard to a mouse/touchpad. Apparently you don't know keyboard shortcuts.
Touchscreen ultra books=net books=fad
Everyone should learn keyboard shortcuts. I actually find it frustrating when I work with someone who has the keyboard/mouse and isnt using them. It just takes forever to do anything. But alas you cant move a cursor to a point on another window quickly with a keyboard.
Distance of hands to screen also isnt that great. We are after all talking about a device where the keyboard is connected to the bottom of the screen. The comparison also isnt just distance of your hand to the screen vs hand to touchpad. When you get to a touchpad you then have to move the mouse on the screen, thats where touching the screen can become faster than a touchpad.
Anyway people can debate whats better and have arguments on either side. The only real way to tell is to use a machine with a touchscreen for a month and at the end see if you ever touch the screen. I do, so on that basis I think theres a strong case for touch screens.
