You don't need to watch the "I'm a Mac, I'm a PC" commercials to see that Microsoft is taking a beating. You see it in the company's financials where its online unit, incredibly, is operating at a loss; overheating Xbox 360 consoles find the company taking a huge warranty hit for a system losing market share to the Wii; and the upgrade wave of its flagship operating system has been more of a ripple than a tsunami.

In fact, even Microsoft will tell you that its fortunes peaked several months ago. After a blowout fiscal first quarter (that ends in September for Mr. Softy), the company's guidance implies a 12% to 14% top-line gain through the final nine months of the current fiscal year.
The article goes on to point out that their competition gets all of the critical praise -- critics don't praise MS software like Vista, but they often praise Adobe/Apple software, for example.
It's a brutally frank glance at Microsoft, but it's complete with a "rebuttal", which doesn't really rebutt.
[edit]
I should clarify: MS' financials were 'positive', but not great considering that Vista sales were supposed to help them significantly. If you look at MS over the last 5 years, it performs well under the S&P 500. Other companies are doing a lot better and MIcrosoft is possibly in danger of slowly losing its golden goose. I think that's the Fool's point.
