I love my K Touch and Fire. Fingerprints are a non-issue with the Kindle Touch and very little movement of one's digit is necessary to turn pages. The Fire, as with any glass screen, can pick up fingerprints depending on how clean one's hands might be. I see only a few fingerprints when navigating the Fire and what little exists is quickly wiped away with a small microfiber cloth.
I haven't touched my Kindle Keyboard but I do still use a DX. Love the Touch and I will not go back to buttons.
