I felt that the new-form-factor 12.9-inch iPad dramatically strengthened the argument for an iPad over a laptop for those with relatively basic needs. I did, however, feel compelled to make the case for an iPad-specific version of iOS, so that the software would do justice to the hardware.
While the iPad Pro isn’t trying to be a Mac, it is a grown-up device and it needs a grown-up operating system. Not macOS, but rather a tailored version of iOS, designed to take advantage of the additional capabilities of the iPad. What some people have termed padOS.
