Exactly. And whether beta or production, fact is that ANYTHING shown by a mfr at CES or the like is a very carefully hand selected set.
You know how some people wind up returning 2, 3, 4 sets before they get one whose clouding, flashlightng, banding, whatever is acceptable (and I'm not just talking about Samsung here)? Well that's what the mfrs do for the CES sets, except they don't have to ship them back and forth like we do
I truly hope Samsung has gotten stricter about QC and/or changed processes, But we won't know until the owners thread is or isn't filled with bitching
