So there are a few new developments, none of which have been widely released. Hardly the big trend of 2019.
With 2019 a third over, it would have to be ramp up pretty sharply to be a "big trend". Maybe it'll be a big tend in announcements, followed by a big tend in actual purchases for 2020 rather than 2019.
I love this! In particular i'd love to see a version of the Purism Librem 5 phone with EInk display.
I'd be down for this, if they were only available in my country.
