I waited a while and was very hesitant to buy this because of all of the negative reviews about the screen problems.  I have a lot of Nook books which I have been reading on the Ipad Mini but I do a lot of my reading at night and the backlight is too harsh for my eyes after working at a computer all day.  I finally decided to take the chance and purchased the Nook Glowlight.  I've had it for three weeks now and so far so good - though there is a little tiny pin hole on the screen.  I had asked the customer service person at BN about the problem and she said it was just a bad batch early on and the problem was fixed.  We'll see.  I did purchase the extended warranty just in case and figured if the screen does fail I'll just give up and use a clip on light.  I like the Nook.  I like the size, the feel and the page turn buttons.  I really hope this device holds up.  It deserves to have a good following - but BN needs to step up and commit to solving whatever is wrong.  If their devices are not selling well it's because they are lagging behind in the solutions and they are only hurting themselves.
