Sony? What Baloney!
I could go on all day about how Sony lost its lead as the premier electronics company of the world, but many an article has already been written about their problems.
As for VAIOs, I learned my lesson the first time I tried to repair one years ago. The biggest problem is there is nothing industry standard about them. You need a part? ANY part? Sony ONLY.
Off sizes, specialized connectors, weird voltage specs, you name it. Market lock in is good... if you are the only game in town. And the performance was nothing special.
These days, Sony anything is overpriced for what you get. And that includes their professional gear as well.
