Congrats on cracking whatever privateframework to make this work!
I went from macbook to a raised, close-face Linux tablet for my outdoor computing setup (and have been thinking about hi brightness since the MSI Creator 17 and iPad pro 12" came out last year).
There's the book mira 13" (and 25") and dasung paperlike 13", which is much better than earlier years but even then they have their classic eink quirks (resolution isn't going to be as good as a hiDPI display, they also need some input power to do eink at high refresh modes, etc.). Plus it's yet another thing to carry.
I've had a 'good enough' experience so far with the raised tablet setup outdoors and an extra battery.
There has to be dozens of us. I also work in the Denver Botanic Gardens, so nice.
As an aside, does anyone know what's up with the linguistic difference between Botanic and Botanical -- Gardens --... are both correct? When speaking, all my friends say "botanical gardens" but every gardens I've been to says "botanic gardens" on the placard.
It’s so good to not have to squint on that colored text with less contrast.
