“If I have any serious illness, or something coming up of an important nature, an operation or anything like that, I think the thing to do is just tell the…the Berkshire shareholders about it. I work for ‘em. Some people might think I’m important to the company. Certainly Steve Jobs is important to Apple. So it’s a material fact. Whether he is facing serious surgery or not is a material fact. Whether I’m facing serious surgery is a material fact. Whether (General Electric CEO) Jeff Immelt is, I mean, so I think that’s important to get out. They’re going to find out about it anyway so I don’t see a big privacy issue or anything of the sort.”

– Warren Buffett says Apple has been too secretive about CEO Steve Jobs’s health issues

Among those who’ve suffered grotesque losses: Microsoft (MSFT) co-founder Bill Gates, who ranks first on the Forbes list with an estimated net worth of $40 billion despite seeing his fortune decline by some $18 billion. Just behind him, in second place: Berkshire Hathaway Chairman Warren Buffett, who saw his net worth fall $25 billion to $37 billion. Finally, telecom magnate Carlos Slim Helu placed third, with $35 billion, down from $60 billion. Combined losses for the three: $68 billion.

“The world has become a wealth wasteland,” Forbes says in its report. “Like the rest of us, the richest people in the world have endured a financial disaster over the past year.”

If seeing your personal fortune slip to $40 billion from $58 billion is disaster, it’s one I think most of us would happily endure.

The same can apparently be said for the PC market. Research outfit Gartner on Monday warned that PC sales will suffer the “sharpest unit decline in history” this year. Gartner (IT) expects the PC industry to ship just 257 million units this year. That’s an 11.9 percent decline from 2008, one that easily eclipses the previous worst decline in 2001, when shipments fell 3.2 percent.

“The PC industry is facing extraordinary conditions as the global economy continues to weaken, users stretch PC lifetimes and PC suppliers grow increasingly cautious,” said Gartner research director George Shiffler. “Slower GDP growth will generally weaken demand and slow new penetration, lengthening PC lifetimes will reduce replacements, and supplier caution will keep inventories at historic lows.”

I’ll say. Gartner believes desktop shipments will decline a staggering 31.9 percent from 2008. Even an expected 80 percent spike in netbook sales, the lone bright spot in the market, won’t do much to temper that. Bad news for PC manufacturers like Dell (DELL) and HP (HPQ), and for suppliers like Microsoft (MSFT), Intel (INTC) and AMD (AMD) as well.

The new economy is the Internet Economy. The Internet Economy is reshaping the fortunes of business, countries and people, leveling the playing field for everyone, and driving the most significant economic shift since the Industrial Revolution.”

– Cisco CEO John Chambers, Sept. 24, 1998

When he appeared at our D5 conference in May 2007, Sen. John McCain said that, given the chance, he’d hire Cisco CEO John Chambers for his cabinet. Now, in the run-up to the November presidential election, it looks like Chambers has some competition for that spot. In an interview with Reuters today, McCain said that Chambers–who’s contributed quite a bit to the McCain campaign–is still on his short list of potential Treasury secretaries, but the Cisco (CSCO) CEO has some company. “I think it would be someone that Americans would recognize that would inspire trust and confidence,” McCain said. “There’s people like John Chambers, there’s people like [former eBay (EBAY) CEO] Meg Whitman, there’s people like Warren Buffett.”

Apparently, current Secretary Henry Paulson doesn’t quite cut it anymore. Anyway … it’s curious that McCain would include Buffett among his choices for Treasury secretary since his appointment would almost certainly outrage tax-cutting fiscal conservatives to near-aneurysm. Indeed, it already has. Said Grover Norquist, president of Americans for Tax Reform, “Warren Buffett is a goddamned Democrat and he doesn’t understand that a 28 percent capital gains tax would be a bad thing. He might be a good bridge partner, but he’s awful on policy.”

Incidentally, Barack Obama’s list of potential Treasury secretaries includes no Silicon Valley CEOs, current or otherwise. According to people close to his campaign, it includes New York Federal Reserve Bank President Tim Geithner, former Treasury Secretary Larry Summers and former deputy Treasury secretary Roger Altman.

Microsoft chairman Bill Gates may be wealthier than you or I, but he’s not wealthier than Warren Buffett. The Berkshire Hathaway boss has overtaken Gates as the world’s wealthiest man.

According to Forbes, Buffett is worth $62 billion. Gates is worth just $58 billion, which puts him in third place on the publication’s billionaires list behind Mexican telecom mogul Carlos Slim Helú (but 782 billionaires ahead of Facebook founder Mark Zuckerberg–YAY!). Interestingly, Gates might have remained richest man in the world had Microsoft not made its hostile bid for Yahoo. (Damn you, Jerry Yang.)

Anyway … for Gates, who’s never really been comfortable with his ranking in Forbes’s annual encomium to obscene wealth, this is likely a welcome dethronement. Asked once if he would be upset if someday he were no longer the world’s richest man, Gates replied, “I wish I wasn’t. There’s nothing good that comes out of that. You get more visibility as a result of it.”
