I loved kindle books as I had taken subscription for an year and it was fun. There is an option of unlimited kindle where you can read as many books as you want. You can learn so many things when you read and kindle has really helped me do so.really happy with the books reading as you and download upto 10 books and keep buying new books as many times as you want. I am already planning to renew it again. You can use your mobile as well as desktop to read the books. Kindle even gives you the option to sell your ebooks. So if you are planning to write a book in future then its worth it. You can keep searching for as many categories as you want and enjoy reading. Only a book lover can understand how it feels to have kindle as an option for reading.
