Microsoft makes a ton of money, no one will deny that, but they make less money than they used to. It's funny how the OP shows the financial numbers for one quarter and says the "the trend here is clear". You can't determine a trend on one quarter, you have to compare to other quarters.
Here are some numbers from Google Finance (http://www.google.com/finance?q=msft)
The first number is Q1 (Mar '12), the second is 2011
Net profit margin 29.34% 33.10%
Operating margin 36.62% 38.83%
Return on average assets 17.80% 23.77%
Return on average equity 30.86% 44.84%
Looks like the trend is down.
Also, their stock price has been basically flat for 10 years. That tells you what the market thinks of Microsoft.
