According to this, the IRS has a separate computer to track his taxes, because their normal computers can't handle numbers that big. Says Gates, "My tax return in the United States has to be kept on a special computer because their normal computers can't deal with the numbers."

OK, two things: 1) I realize the guy has a ton of money ($47 billion, according to Forbes), but if the IRS can't handle that, it's a problem with the software, not the computer. And the fix they'd install wouldn't disable the software for the rest of us, so why would they need a separate computer? And 2) Shouldn't the head of Microsoft know this? And if they are using a separate computer for his taxes (for whatever reason), shouldn't he be able to explain it better?
