I’ve been baited into writing about touch screen Macs once more

I don’t think these Macs would look like today’s clamshell MacBooks, they would have a new form factor more similar to iPads.

What if a touchscreen Mac only allowed for scrolling content with fingers? If the touchscreen Mac is not convertible, what other use of touch than scrolling would people do with a touchscreen Mac? What are people doing on Windows with a touch screen, really?
