Nope, Apple made it clear they tested Mac OS X on a touchscreen device. And it sucked. Rightly. Because Mac OS X is designed for one point of input at the size of one pixel (and because at the time, it was Panther, but that's secondary).
Doesn't stop them from making a completely new desktop touch OS.
What part of my statement do you have disagreement? I stated clearly that they have 2 different UI Paradigms and you say, ``Nope,...'' and reinforce my statement by reciting what Craig Federigi [former colleague of mine] stated during WWDC.
By my citing the 2 different UI paradigms I'm making it clear that Apple [like Craig cited] has deliberately split the two markets where the embedded space is a touch space and the Desktop/Laptop is a hybrid mouse/touchpad/glidepad space.
I'll be more clear: iOS is Apple's Consumption OS. Mac OS X is Apple's Production OS. Portions of iOS extended from OS X make it a partial production OS but never will it be that of OS X.
No one will be sitting in from of a 30" screen and typing on it. Nor will they ditch the keyboard for some large glide pad only where I can get a virtual keyboard and type on it ala Star Trek, all in a price point at today's prices or less.
This isn't Star Trek where everyone on the ship is just working in their assigned control panel or Johnny Neumonic where we have roll out keyboards with perfect sensor response interfaces that react instantly like a physical keyboard does.
