Very happy with my Kindle. Got fed up with the unreliability & problems of our Kobos & converted all our books to Kindle format. I have used it for a month now & not a bit of trouble. My wife was given a 3 year old unused Kindle at the same time & has had no problems with it either. They update & download books from Amazon seamlessly. Useability of it & battery life (in airplane mode) are quite good.
