also it weighs 300 grams for 40 cells (about two thirds of a pound).
Also the Orbit Flow is really cool. Its a 40 cell display with three buttons on each side, with maybe half an inch of blank metal above it. It has no battery or keyboard and connects with USB C. I could see putting this in front of my keyboard and having a very comfortable setup, a lot better than putting a display with a Perkins keyboard in front of a QWERTY keyboard because the Braille is a lot closer to the keyboard with the Flow. It also has cursor routing keys of course. #NFB26
