My dad otoh cannot stop. Whenever he uses his retina MBP after using an iPad he immediately tries to scroll on the screen lol.
I do this as well. Unfortunately many here are invoking the straw man argument that a touch screen would be used for the majority of the input, rather than an option for those times when it makes sense to intuitively touch the screen.
That would suggest that many users would find a touch screen on a Mac to be entirely logical and intuitive.
Yup. I find it quite natural after years of being conditioned to use touch screens just about everywhere, and in many cases, preferable to clicking and scrolling.
The idea that it takes more effort to lift my hand and touch the screen is more fatiguing than holding an iPad and touching it is silly -- and that is a situation where 100% of the input is by touch. Moreover, proper hand position is not resting them on the keyboard. If the hands are ergonomically floating above the keys, touching the screen is actually going to be more efficient and easier, than shifting into a trackpad position, or moving the hand to manipulate a mouse, and finding and navigating the cursor where it needs to be -- just point directly at the screen where you're already looking and touch it.
Once iOS apps start appearing on the Mac, it's going to get very confusing when a familiar touch interface can no longer be touched, and instead a mouse or trackpad will be necessary. It's also going prove that there's no reason iOS can't use a mouse or trackpad to navigate it when that would be the most natural choice.
