There is a lot of investment in the USBs.....
This article is incredibly biased. For a start, Thunderbolt is a proprietary technology, and has presumably been developed in conjunction with Intel in order to make problems with Microsoft as much as offering users anything. The author should remember that there are billions of little bits of wire connecting all sorts of equipment using USB plugs and sockets. This is just another case of an attempt to divide and conquer, as has been seen throughout the history of IT whenever a supplier things that they are strong enough in the market to get away with it. Looking at raw speeds, a factor of two is hardly worth ditching billions of bits of connecting cable. Apple is just continuing at its dirty tricks of making everything proprietary under the guise of making it slick.
