Lauren Goode, interviewing Craig Federighi for Wired:

When addressing my question about whether iOS apps moving to macOS is a natural precursor to touchscreen Macs, Federighi told me he’s “not into touchscreens” on PCs and doesn’t anticipate he ever will be. “We really feel that the ergonomics of using a Mac are that your hands are rested on a surface, and that lifting your arm up to poke a screen is a pretty fatiguing thing to do,” he said.

Federighi added that he doesn’t think the touchscreen laptops out there today—which he referred to as “experiments”—have been compelling. “I don’t think we’ve looked at any of the other guys to date and said, how fast can we get there?” (It’s worth noting that Microsoft’s Surface laptop, which has a touchscreen and is considered a top MacBook rival, has received largely positive reviews.)

The Surface Pro’s and Surface Book’s weakest link is that they are poor tablets for users like me, but I can easily imagine a scenario where iOS (iPad) apps on a detached MacBook Pro screen would allow me to replace my iPad, while simultaneously allowing me to run full desktop software, such as Lightroom, should I need it.
