You know, I still disagree with you but I think you're arguing from a completely biased standpoint.
I looked through your all of your previous comments and noticed that ~85% of them were on Apple related submissions.
So while I'm not going to blatantly call you a Fanboy, but... where there's smoke...
As for Microsofts revenue decline, they had a bad product with Windows Vista.. they did the same thing before with Windows ME and I'll hazard a guess that they'll probably screw up several OS's in the future.
The fact is, sometimes top tier companies make products that don't gel with consumers.
Recent examples? Microsoft with Vista, Apple and the Apple TV, Google with Knol...
While we're looking at company's failures, lets just ignore Apple's track record when Jobs wasn't there shall we? I mean, its not like they've had any bad products before </sarcasm>
Even still, Vista was released in January 07 (source: Wikipedia) and Microsoft managed to have at least 1 full year of high growth during that time, which is assumed to be during the "bad time" of Vista. So you could realistically argue that this years numbers were a result of recession.
(I'd suggest that Microsoft's OS and the budget PC market is more sensitive to financial downturns than Apple given it's marketed towards people who have smaller incomes than your typical Apple consumer, thus people are less likely to buy Windows based PC's when times are tough. That's just conjecture on my part though)
Microsoft isn't on a long slow decline, it's a bump in the road, plain and simple.
This article was nothing but propaganda (or blatant fanboyism, take your pick).
"The core of Gruber's argument is that Apple's market share (not Google's) is growing quickly, whereas Microsoft's is falling."
He compared Google's revenue growth to Microsoft's (6th paragraph), so I figured it was fair game to compare the two. I never compared Apple's revenue to Microsoft's simply because I haven't bothered to look recently.
I just know these figures when I looked to verify or disprove a Google fanboy's comment previously on HN
