There are a bunch of new Kindles coming out...very exciting. I had a K1 until I broke it, bought a K2 and now I want a kindle Fire. It's 1/2 the price of an Ipad and uses wifi. I have an Ipad already, I just like to buy toys.
You can get a Kindle app on the iPad too. I have one cause I broke my Kindle. Kindle rocks but I don't know anything about the touch versions. I had to stop buying them after I broke the second one. :P
