Got my Boox Note Air 4C yesterday! It feels very solid and premium and the e-ink screen is great! I used it a bit before sleep last night.
It's just a bit heavy to hold with a single hand for a long time. But given its screen size it's probably unavoidable.
After some trial and error I figured out a way to get all my kindle books downloaded and DRM stripped. I also managed to use Libby for Boston Public Library!
Gonna read more this winter!
