I know you said you’ve ruled out Onyx, but I just purchased the Boox Palma, and I really can’t complain about the quality of the device. It’s light years ahead of anything by Kobo, which I was considering.

In this case, a good pubic education.
It’s not 32 bit computers, but computers with a 32 bit BIOS clock. There is fortunately a difference.
