I'd like to know what all those sellers are thinking. Really! I mean, look at this chart. There we have it, down down and more down. MSFT is now at its 52-week low -- in fact, the stock hasn't been this low since October 4, 2002. I know! Today, the stock closed at $23.17, down 3.5%. It's now trading 15% below its high last week. Ouch. Guess everyone does believe Gartner's report about Vista delays.

Those who are selling right now? In my opinion, it's irrational depression. Why sell at the low? Panic, I suppose, but it seems highly, um, foolish. Tim Beyers, he who is Motley Foolish but not, you know, foolish, agrees. He argues that, even if you buy the idea that Microsoft might be taking second fiddle to Google (the Evil-Empire-come-lately), it's still a good company to own. After all, they are rife with cash-ola and they absolutely, totally dominate the average laptop. Come on now, look around you at the coffee shop. How many laptops don't have Windows-based software?

Unless you're tapping away at my favorite worker-owned coffee collective (where everyone either has an iBook or a built-from-scratch Linux geek-machine), the answer is: few. If I owned Mr. Softee right now, I'd be holding. And if I owned a pile full of cash right now, I'd be buying. There may be more down. But I'd bet at least some of my children's future on the long-term up.
