I think colored eink is a great idea, unfortunately I will never buy a boox device at this point. Their business model is similar to phone model, pushing out new model is much more important than maintaining old model.

IMO this practice is very wasteful, extremely bad for the environment (electronics are in general very toxic), and ultimately just anti consumer.

That being said, different people have different needs, and have to face different trade-offs. Absolutely no judgement if anyone decided to get one. I am just saying personally I would much prefer the supernote's business model than boox.
