Can somebody explain to me why this guy is still a billionaire? I used to read many years ago about his business of renting computer terminals for the same price for which you could buy equivalent generic hardware outright. The big selling point (or renting point) of this 1970s-sounding business model was that was the only way you could get Bloomberg's proprietary content. I figured his business might last a couple of years longer than all the comparable ones out there before being wiped out by open standards approaches because his market was Wall Street traders, who have more money than God, so they weren't in a hurry to give up a system they were familiar with just to save their employers $10,000 each per year or so. But, I gather, he's not only still in business, he's still raking in the billions. What's the deal?
