[Michal Jancik]

As a long-time Pocketbook user, what bothers me most about PB devices is the slow OS, navigation and everything about it is terribly slow compared to the competition.

The battery life and PDF functions are competitive, but the book format is empty in the settings, for example you will not find the option to set the font weight and the like.

Then, my personal complaint is that I don't like the way books are moved in the library, I almost always don't see at least half of the book image.
The entire navigation in the menu is so clumsy, but listing books by: size, name, addition, etc. is good.

I have no experience with Android readers from PB. I would probably be very interested in the battery life.
