"Bad" is a poor term to apply to the K3's PDF functions. The K3's PDF rendering is not in any way "bad". In fact, it renders most PDFs very well.
What the K3 lacks are the various "crutches" that aid in viewing inappropriately constructed PDFs (e.g. those built for letter-size pages, textbook sized pages, ...) to be viewed adequately on a small screen.
While you will find some readers that have a better toolbox of such crutches, absolutely no small screen (read: 7" or smaller) device is better than passable when given the job of displaying most of the PDFs out there. If you want good or better PDF display a 10" or larger display is an absolute minimum requirement.
