OP here. Definitely some improvements... but (at least in my eyes) incremental.

Notebooks are pretty sweet, but in the hands of very few. They're definitely growing in popularity, which is great.

But even the "notebook" concept is a very limited "low pass filter" version of the visions of Engelbart, AKay, TN, etc.

The video that AKay has been sharing around in the post than @dang linked to[0] is a great example of what's not-even-close to possible on today's systems.
