Using an iPad or Nook to read a book is like using a multi-tool when all you need is a screwdriver. Sure it works, but it's awkward. Alton Brown may believe that in the kitchen you shouldn't have a singular use tool, but I disagree when it comes to reading.
When I read a book, I want to read the book! I don't want to play games on my book. I don't want to watch a movie on my book. I don't want to get on the internet with my book.
Before my Kindle I would bring a book with me when I traveled. If I was close to finishing the book, I'd debate if I should pack a second book, or pick up a new one at the airport. Picking up a book at the airport is always a gamble. You never know if there will actually be something there that you want to read. Packing a second book just meant more stuff to carry around. Having my Kindle means I can easily carry several books with me or even reload an old one that I want to read again. I can also read my friends WIPs (works in progress) or edit my own stories.
So, if you're looking for a great way to have your library with you at all times and capitalize on the ease of grabbing a new book, in my opinion, Kindle is the way to go.
