I didn't buy the Nook backlight because 1/2 of 500 people said they did not abuse it and still it had pinholes in the screen lighting coming through and it was more than annoying... it's broken. This has been documented now... I saw a techee take it apart and compare it to the STR and it uses a totally different screen material and backing.
People who bought it took it back 1/2 the time and I am not buying it because I live in very rural area and don't want the hastel... I am buying STR for price, dependability and waiting for better quality lighting screens, technology that doesnt break so easily
