My opinion is this: If you haven't already bought a Kindle, it's likely you still won't. If anything these new touch models are finely catching up to the Nook Touch. The only real incentive is the X-Ray feature, something B&N can easily do as well with a update. Otherwise there's really nothing new here to be said for the Kindles.
Comes down to you liking Amazon's store, their format, and their eBook practices (which I do not, which is what held me back on them.)
Right now I just want a good cheap tablet so I can have both BN or Amazon if I choose.
