Also, I'm not sure what Alan Turing has to do with Sinclair and Amstrad failing and Dell being successful. From what I understand of the early development of the computer, much more work was done in Boston, NY, and the Valley than in the UK.
But pg's point was specifically about how the Euro top ten was dominated by old companies and boring business models. My point is that aside from google, amazon and Facebook, the US top ten is not all that hip and fresh either.
That's a pretty big aside.
