E-Reader |  | Kindle | I began using all the e-book apps, iBook, Nook, and Kindle in the very beginning, but I have since become a Kindle enthusiast for a couple of reasons. First of all, I like the selection of books offered by Amazon, and secondly there are some great browser extension apps that make sending documents to read in your Kindle app easy to do.
