Query: It's the best!

This is the absolute best thing ever invented! I am an avid reader with a doctoral degree in literacy and I love the ease in which I can purchase books (even at the beach!), adjust the font size (my eyes are not what they used to be), and have multiple titles at my fingertips (sometimes I like to sample a book before I read it.) I have owned one since December and have been reading more than ever. I have amazed my book club friends with how I can bookmark a section without Post-it notes! I appreciate being able to read a 1000 page book without having to hold a heavy volume. My vocabulary is growing since I can look up a word in an instant. If you love to read, this device is a blessing. My only disapppointment is that there are some books that are not available for my Kindle. I am hoping Amazon will rectify that shortly.
