I have to admit a similar experience. I haven't even played with my wife's new PW for five minutes, but today on my trusty K3 I was momentarily stumped when I wanted to see "more" of a word definition. On the screen it said "More <-|" - meaning that I was supposed to hit the arrow/Enter key - but I reached up and touched "More" on the screen and forgot for a moment that there was a button with the arrow on it!
It doesn't take long to become "touch-stupid!"
Anyway, my wife does love her PW upgrade from her K2 and the screen itself does not seem to have the dreaded defects - at least not to the extent that either of us notice.
And she hadn't even finished unwrapping the PW for her birthday before two of the (adult) kids were putting in claims for the K2.
