What are you talking about. Sony is King in DSLR sensors and their cameras are quite awesome. esp in cinematography applications. TVs sell just the same, headphones as well (i have 3 sony headphones). "Component sets" are pretty much a thing of the past now and they used to dominate there.
Sony phones are crappy now still just the same thing all over again no innovation. They Tried with Vaio but the price/performance ratio was BS.
What the hell are you talking about? Failed at everything? seriously?
