And also Booxstor deserves the money for units sold.
He did and he does for Onyx e-books development a lot.
And he passively and also actively supports
all users, not only his (or his distribution channel) customers. I did not buy from Booxstor (because I did not know his shop that time), but I get support. Many of my suggestions and wishes went to firmware. And few little things that bothered me were fixed/changed within several days. What else one could wish?
