This device is obviously a non-starter, iPads exist already, and the laptop form factor isn't right for this ergonomically.

iPad and Macbook should've already converged at this point.

I say that even as a very happy user of a Macbook with the fancy non-reflective screen coating that wouldn't be a thing on a touchscreen.

I expect the new cheap Macbook that's rumoured will be a hybrid.

Nicer windows laptops have had this for a long time and it works great, other than the janky OS and app support. Just being able to lazily scroll content is worth it some of the time, and there are no downsides. Just like having built-in 5G networking, it's a bizarre blindspot for Apple.

My old-ass Chromebook Pixel (retired due to Chrome no longer having worthwhile adblocking) had a perfect form factor for hybrid tablet/laptop use, though not the software - Beautiful 180 degree hinge, 4:3 aspect ratio.
