My understanding is that there are actually 4 sets so far - two 43 and two 50 inch. Apparently there are some important differences in the video scaleing hardware etc betweeen the versions.

I've never laid eyes on the Sammy, but the other DLP I've seen is encouraging. One obvious thing was the nature of the picture - they just don't look like glowing tubes. To me the colors in the DLP systems were more 'film like' for lack of a better term.

Once they mature I think there is great potential.
