My brother bought two flat screen TVs last year, a new 3D 55" Samsung to replace his old-old Sony in the family room and a new 46" Sony for his bedroom. He bought the Sony last summer and the Samsung this past Christmas. Two weeks ago the new Samsung went out on him prematurely, the Technician came over and replaced a flat retangular piece in the back side of the TV, no one knew what that flat retangular piece was. This is his first Samsung and I bet his last. Samsung may have attractive products, but for quality wise, Sony made better products than Samsung.
So what? Samsung is absolutely running away with the field. Check out Amazon and look at the listing (changes hourly) of the best-selling TV sets. If you find a Sony even among the top 50 I'd be surprised. What sets aren't being sold by Samsung are being sold by Panasonic, Vizio, LG, and Toshiba. Sony no longer commands the public's interest or trust.
