Sure, but Apple also said that no one wanted a stylus on a tablet. If the technology and market exist to do it well and make it a success, they'll make it. Touch and pen manipulation on laptop and desktop screens so far have done little to show that this is something any significant portion of the market actually wants.

Personally, I have two touch-enabled laptops and the only time I interact with the touch screen is when I try to point at something in conversation and am unpleasantly surprised when it moves the cursor.
