From the article: "Adobe Systems ranked number 91, and other familiar companies, like Dell and Microsoft, were not on the list."

Of course not. They're hardly growing, if at all. They're essentially treading water, sitting on a huge market share. The percentage of PCs that come with Windows installed is dropping as some manufacturers sell PCs with Linux installed. The usage of MSIE is dropping steadily. When you're on the top, it's hard to go anywhere but down. Go check Microsoft or Dell's stock vs Apple's. Sure, Apple has been sliding since about January, but Dell has been sliding for a very long time. It's price is about 40% (reading off a graph) lower than it was a year ago. Microsoft is also down, maybe 5%. Apple is UP about 55% from a year ago. On a 2-year basis, Apple is up more than 300%, while Dell and Microsoft are both negative. Given the performance of Dell, the stockholders should revolt and fire the entire board and all the executives.

"Of course not. They're hardly growing, if at all. They're essentially treading water, sitting on a huge market share."

Considering the fact that companies like Microsoft often get to where they are by buying up (and stealing from) the compitition, it is pretty hard to grow now that all the companies that you got your ideas from are gone.
