Boox Firmware Version 4.2

👍 Recommended

The Boox firmware is very comprehensive and feature-rich, which (along with the ability to install third-party apps) makes it one of the versatile e-ink tablet brands available.

The software can feel a little non-intuitive in places (perhaps as a result of Boox trying to cram as much as they can into the system), and it has a much steeper learning curve than other brands.

Boox tablets are best for users that want to do more than just read and write with an e-ink screen.

Pros

+ Android (supports 3rd-party apps)
+ Great reading software
+ Fantastic note-taking software
+ Very powerful and versatile

Cons

- Steeper learning curve
- Not as intuitive as it could be
