4.5 It worked well for 1 year... LondonCarlos | 22/07/2011 | See all LondonCarlos's reviews (1) I got this 14 months ago and I was very happy with it. Text not as sharp as the new kindle, but it was good enough. However, couple of weeks ago, the bottom left corner of the screen got lots of black lines that wouldnt go. I tried resetting, reinstalling the firmware...nothing. And yesterday, the whole screen got really really dark and it's almost impossible to read. I can't find any information on how to sort it out, and since the product is not on warranty anymore...well, I think I'm going to have to move to Kindle!
