What the author wants is a 2-in-1. The iPad is that, it's just hobbled to be a really bad laptop. All the hardware pieces are there, the power, the keyboard/trackpad accessory, the touch screen, the pen. If you go look at the marketing for the iPad line it really does seem like maybe you can do anything with them. It's only once you get serious that it all falls apart due to the software.

The iPad Pro was designed to compete with the Surface Pro and it simultaneously does and doesn't. Anybody who expects more than a tablet with pen input will be disappointed or frustrated eventually.
