Who cares about the thinness, the LED and the "Hz" whatchamajigger technology produces a superior picture. I saw these sets at Sears a few weeks ago and they are GORGEOUS!! The picture is stunning beyond words - I felt like reaching into the screen to tap the people on the shoulder! The LED Samsungs were all getting better shelf positions than the competition and for good reason; they made the nearby Sony's look washed out and blurry with really top notch sharpness, clarity and depth. I was chatting with the salesman (who also has one on his wish list) and apparently it has to do with the black level - even blacker than the plasmas which are apparently yesterdays news already.
Seems like Samsung is today what Sony was 10 years ago. Though I used to feel comfortable paying more (quite a bit more sometimes) for the brand, gone are the days when all my electronics say "Sony"; they simply aren't turning out the quality that they used to. 'Bout 8 years ago, I stood in CompUSA for nearly 4 hours debating whether to by the samsung 170MP or the equivalent SONY model because I couldn't believe that I felt the Sammy had a better picture. I went with the Samsung and never regretted it. Since then I have several Sony products go irretrievably south on me (most regrettably my Trinitron).
I like the picture quality on the Sammy mobiles, too, but they are a little too light for my tastes. I'm glad the TV's have some heftiness to them; for some reason I feel like the heavy stuff lasts longer than the plastic counterparts. They are not cheap however - a replacement for my departed 35" Trinitron will have to wait for better days.
Oh but how I want I want I want!
