Lenovo has released a Yoga convertible with an E-ink display.

Interesting.

Basically two displays: primary IPS and secondary E-ink. But keyboard is… virtual, you type on e-ink.

You don’t are not limited to typing on the e-Ink it can be used for to display documents, to take handwritten notes etc.

Tried it this summer with 13'' Onyx Boox 2 as hdmi display and standalone. Both worked as expected, but somehow getting things done didn't really work well.

Interesting. Nice to know someone has used the 13" Onyx outside for work.

Curious - why didn't it work for you?

Not onyx fault: It was just too hot;)

Display is perfect in sun, but contrast not optimal in shade, so I couldn't escape the burn. Next time I try a 20m hdmi cable with normal display set to max in the shade.

I work outdoors every day when it’s warm enough, from a hammock. I use a 13” MBP. As long as you’re in the shade it’s great.

Polarized sunglasses help as well, and I have a color scheme for my terminal that’s dark-on-light that I switch to when it’s bright.

Yea I work outside in the shade as well sometimes. It works pretty well with a bright monitor, but you still have to be in the shade. I'd like to be able to soak up a little sun, while working.
