It's like Schiller is being deliberately disingenuous. People don't want a touchscreen Mac so they can lean over the keyboard and touch it while it's on their lap/table. That is indeed uncomfortable, though it must be pointed out that is what Apple tells iPad Pro users they should do (that keyboard desperately needs a trackpad).
People want a touchscreen Mac so they can fold the keyboard out of the way/detach it and use it as a tablet, so they don't have to cart two devices around if they want to read in portrait mode.
Or does he really understand customers so badly? Well, that would explain the Macbook keyboard debacle.
This right here, I can agree with. The potentially disingenuous part is stemming from the fact that Apple wants to sell you two devices. I would love a device the size of the rMB, where when the screen detached, it automatically switched to iOS. Now, I am no engineer and can think of a number of issues with this. Mainly around size and weight. I think when this can be done, we may see such a device.
