IMO, no eInk reader has ever gotten a built-in light to work without seriously degrading the text. I know there are a lot of diehard Paperwhite and Glo fans out there who argue against that statement. That is until they pick up a Nexus 7.2 or an iPad mini Retina, then they finally see what clear, sharp, beautiful text really looks like, and thereafter their Paperwhites and Glos sit collecting dust on a shelf.
