The Kindle ebook format has completely changed how I read. Instead of carrying a book everywhere with me, I now read my current book on the nearest electronic device. My sister gave me the first Kindle, because she could see how perfect it was for me. I took that Kindle on my next three week business trip to China and did not take a half a suitcase filled with books. (Not many English books in the Shanghai bookstores)
I read my Kindle books almost anywhere - in line at Disneyland, on the plane, while waiting to pick up my daughter, and now - in the pool. On Amazon
