I'm desperately awaiting the perfect eink device for this.
I've got a great writing setup on Obsidian that really works for me, a royal kludge mechanical keyboard...just waiting on the next gen of eink
The Boox One Note Max was sooo close, but they almost immediately discontinued the product and probably won't be supporting it long.
Suggestions are welcome
I use the Onyx Boox Palma for a portable eink drafting setup. It's worked pretty well. I wrote about it here: https://liza.io/portable-writing-setup-with-onyx-boox-palma/
If your up for waiting and the usual crowd funding risks there's https://www.kickstarter.com/projects/zerowriter/zerowriter-f...
I backed it myself.
Ideally, somebody like Modos would create a replacement e-ink display for the Framework.
My wife bought one of these: https://getfreewrite.com/products/freewrite-traveler
Reviews are wildly polarised. * Some folks find it to be the best thing ever [long battery life, the new patch makes the eink surprisingly fastly responsive, decent keyboard, no distractions] * While others find it terrible [it's still eink, that's a lot of money for a device that doesn't actually do much]
