Hi im not great woth computers/ technology but would really like to get a kindle not sure what the difference between they two are and why would you need a keyboard on it anyway? Are they easy to use and to buy the 'e books'? As i said I am really not great with all this technology! Where do you buy the e4 books from and are they the same sort of price as normal books or cheaper? Thnk you (sorry for all the questions) just not sure about ... anything really!
