I am planing to bulk order a good ebook reader. After searching a lot on the web I found Kindle as the best among them all. Now there are two editions in it. The first one is Kindle Fire and the second on is Paperwhite. Can anyone here tell me which one is best among them both. I am just looking for a simple ebook reader which will be distributed among the kinds in my institution. There is a great price difference between both of them. What if I purchased Paperwhite. Is it good for future use also.
