Oop, I just noticed I posted the URL to the Boox Laptop. Onyx has let me know they are not going to produce that one, as now external keyboards can be used via Bluetooth.
I replaced that URL in my above post so now it links to the video of writing on the Max using a keyboard.
This is another example:
"Writing on the e-ink Kepler Tablet from Onyx with BT Keyboard using the Texteditor app."

The letters there appear way much faster than on my Boox M92.
Another one:
"13.3 Inch E-ink As Laptop Monitor"

I'm keeping and eye on this one also:
"Sony is developing an E-Ink Laptop"
https://www.youtube.com/watch?v=NP1Y7QMAah8
This one needs to connect to a pc:
"DASUNG Paperlike------The World's First E Ink Monitor"
(At 2:30)

I guess I just have to have some patience...
