New development for ODK with e-ink tablets?

Dear ODK community,
I am a new subscriber to this forum and have gone through past posts talking about running ODK on e-ink tablets; yet, the posts I saw date back to 2016.
So, here is the question: have there been new experiences with recently commercialized e-ink tablet and the use of ODK on them? Also, is anyone aware of e-ink tablets that come now with GPS capabilities?
We run mostly national surveys across the globe and collecting GPS waypoints is a must, so if the e-ink world doesn't provide this feature yet, we will have to continue with 'classical' tablets.

Thanks for sharing your latest experience on the topic, Fabian
