I find the Brailliant BI a lovely reading experience. The braille cells are crisp and unlike some other displays they do not have that plastic squeaky feel. I love how the display is constructed mostly of aluminium and therefore is quite durable and yet surprisingly lightweight to carry around. Another feature that makes the Brailliant such a joy to use is the signature thumb keys. Your thumbs just fall on them naturally as you are reading on the display, allowing your fingers to stay on the cells while you pan back and forth with your thumbs.
