I can't believe how much owning a tablet has opened my world! I am carrying it everywhere and using it for Internet services I have never used before! The incredible audio and video are the best. I do not have an HD television so the Kindle is better quality! I did not think I would want to read books on it but being able to adjust the type size, colors, and spacing, I am reading constantly! It's a life changer!
