I think they just don't know about the Magic Keyboard.

i bought a magic keyboard for my 11" ipad pro and ultimately didn't use it much. it does have a traditional laptop-style hinge, but the way the ipad mounts to the case brings it forward over the keyboard more than with a regular laptop. the hinge also doesn't allow for a very wide range of motion (even compared to macbooks). finally, the center of gravity is really high compared to a laptop which makes it awkward to use as a literal laptop or when lying down.

it definitely looks cool (i could see the design having been inspired by the OG Mac and 20th Anniversary Mac) but works best on a stable surface; plus if you want to use it purely as a tablet, you're left with a big clunky keyboard case to deal with.

the idea of a laptop/tablet combo is cool but i haven't seen the concept executed very successfully from either starting point.
