I’ve got to say, I love my Kindle. It is very easy to read, and I do like the ability to highlight, bookmark, and take notes, and for them all to sync with the Kindle app on my iPhone and computer.
But, I love actually using the Kindle app on my iPhone (and thus would love even more using it on an iPad). The intractability is second to none. If only it had a camera for Skyping, I would be selling my Kindle online, and going for the low-end iPad.
