I purchased the pocketbook360 mostly because I think Russian programmers are really good (long cold winters inside programming). It arrived this morning. Small, light, easy to read.
I thought something was wrong when I tried to navigate using the center button. The center button did not seem to work for navigating left/right, up/down. I had assumed the center button was a rocker switch, but it's just on/off. Then I realized the silver frame outside the center button was another set of buttons. Maybe I should have looked at page 5 in the instruction booklet

Everything works fine now but I couldn't figure out how to exit the chess game except by resetting to main menu using the power button.
