I made a great discovery~ You don't have to buy a Kindle book reader (Amazon, $79-$199 ) or a Nook Reader (Barnes & Noble, $99-$199) to access the great ebooks available. You can download the applications for free.
Simply download the Applications to your PC (or Laptop)
Barnes & Noble NOOK READER: Nook Reader for PC
Amazon KINDLE READER: Kindle Reader for PC
