Pundits like to blab that Apple should buy Sony. With quarterly profits down 72 percent, SNE's market value is now a stupefyingly low 58 percent of its book value. Steve must be tempted. Buy Sony. Shut it down.Remember the original Walkman? The first Vaio? These days, Sony products don't threaten Steve Jobs. They irritate him. Even Sony knows their stuff's not cool. Look at the photos on their home page: James Bond. Pink. "Try to solve the mystery of the Passengers ... Save the world from bad music." No product shots except a thumbnail-size Playstation HD shoved in the lower right corner. I'm sure the focus group loved it. But to a gearhead like me it screams, "I'm Sony. Please kill me."
