I get overly excited with any e-ink release. Always looking for the Kindle that can do just a little bit more without becoming a distraction from reading.

Also, always looking for a Kindle that's less Amazon-y but still convenient.

It's probably a unicorn. Any Android device I'd probably get distracted too often and wind up frustrated with how poorly the distractions run on e-ink. I suspect that non-amazon e-readers have probably reached whispersync levels of convenience after a short learning curve but don't have any evidence to base that on.

Also, why can't Lenovo follow up the Yoga Book C930?!

Anyway, yay e-ink!

Have you tried a reMarkable tablet?

It's a 10.3" e-ink device with a really nice touchscreen surface that supports low-latency, high-precision writing using a stylus. It's Linux-based and is highly hackable with lots of open-source projects:

It seems to stand alone....

Yay e-ink, boo GPL violations.
