The thing I'd like about FF is really the field of view, and getting the same response from a particular lens at a particular distance from the subject that you would on film.
With portraits, we either have to be a lot farther away or use a shorter lens to get the same framing, and that affects the entire image (depth of field, etc.). The 31 ltd would be a perfect wide on FF, but it's a little tight on APS-C.
But, for the most part, I'm very happy with the performance of the K20, and frankly I loved the images from the K100 too! I don't need more pixels, but it'd be nice to get more "image."
