I worry if that new company will be able to deliver, they are under-cutting the competition pretty hard there whilst simultaneously offering better hardware. And given they are crowdfunding I am guessing they don't have much experience. For these things, I would worry more about the effort that's gone into the software programming over the hardware itself.
I had a much older non-android boox tablet and it worked fine enough as an e reader, the note taking experience wasn't great though. I also have a yotaphone 2 with the e-ink screen. As I have commented in previous threads, that thing makes me feel nauseous - I think its the fuzzy way e-ink animates movement.
