I love my Kindle! I'm on my second one and I would never give it up. I like that it means fewer books sitting around the house that can't fit on my bookshelves. It's great for travel and I can get a book anywhere, anytime, instantly. I still read real books half the time, and I borrow both traditional books and Kindle books from the library. It doesn't feel any different to me to read a book on my Kindle than a traditional book.
I've given them to my DH and all my kids as gifts. We borrow books back and forth between our Kindles.
Kindle is one of my favorite applications of technology.
