I feel bad saying I hate this product because when I first received it I absolutely loved it.  The quality of the GlowLight when used was spectacular, the features where easy to use.  Then tiny "cracks / lines" started to appear in the screen / light which made it difficult to use at first; then as more appeared the device became completely unusable.  This device was not abused in anyway. It was kept in a case, not dropped, etc..  After further searching concerning this problem, it is not uncommon.  A significant number of people reported the same problem even though their care of the device was good.  The most disturbing part of all this is that the manufacturer of the product has known about this problem and to date the item is still being sold with the defect.  I was so disappointed because other than this problem I loved my NOOK Simple Touch with GlowLight.  I now have a Kindle Paperwhite, it is similar to the Nook but just enough difference that except for the defect I like the Nook by a slight margin but not enough to invest in a defective product again.  In addition, there is difference between customer service for both devices. The Nook customer service regarding defects / returns / replacements is poor compared to the good reports of customer service with the Kindle.  Wanted to like the NOOK Simple Touch but couldn't risk it.
