Cellaris, you know me well!
Of course I don't meant to be hurtful, only my blood pressure go very high!
Related to Boox, yes, I know that those devices are "as is". No bugfixing, no improvements, a lot of lies from Chinese manufacturer... Then only sure thing is hardware European warranty if purchased here.
And related to my change, well, I prefer a bigger screen. I know firmware and software are the same in all Boox "generation".
