I got my Kindle paperwhite 6” about a month ago and I studied more books than that I would have studied through hard cover books. I keep it with me all the time and keep studying when I find spare time. Its specialized surface ensures no screen glare that allows me to read even in sun light. Its light is adjustable for day and night both and I recharge its battery once a week even I study several hours a week. Its display is just amazing because of 300 ppi that enhances focus and gives a feeling of reading real paper. Its one month experience helped me to realize that my buying decision was really the best.
