Kindle tablets and readers are great.  Did you know that you can use any tablet to read a Kindle book?  You can.  Just get the Kindle app for your tablet (usually can search on your tablet and download it right away for free).  Then click on the Kindle icon on your screen which you now have after getting the app.  Go to search in the Kindle store.  Find the author your are looking for or just search for childrens' books, etc., and then get the book.  You can get many free books.  If you chose to buy a book you can pay with PayPal or with a credit or debit card. 

I have a Samsung Galaxy tablet and I love it.  I went into the Galaxy store and found the FREE app for Kindle and downloaded it and my Kindle books are great on this tablet.
