I've got my bebook (aka hanlin, lbook) yesterday and I absolutely love it.
I'd like to thank this forum for the support I got in selecting this device.
Feel free to ask me if you have any questions regarding this device.
Re software question: I think this device uses the same firmware with some custom modification by Bebook. Even the software version info has "jinke v3" name displayed on it.
p.s. I've attached photo of my bebook displaying pdf file.
