Onyx iterates on its BOOX tablets fairly rapidly, but tends to continuously offer something in various size classifications. You'll find 13.3" tablets typically named as "Max" something or other.

I do see the Note Max as presently available, FWIW: <https://shop.boox.com/products/notemax>

I've had a previous iteration of their 13.3" tablet, the Max Lumi. Slightly lower resolution, and has a frontlight. It is a very nice display, though with an Android OS which I see as a net negative.

I'd really like an e-ink display option for the Framework 12" or 13" laptop.
