The fact that you think Microsoft is in decline over something as small as what you've posted above is beyond me. You clearly have no idea what you are on about. Microsoft are not going anywhere.not at all.
IBM just surpassed Microsoft in value (market capitalization): the first time since 1996
Apple overtook Microsoft before that.
Investors are calling for the CEO of MS Steve Ballmer to step down

as the article above points out: "An investor who put $100,000 into Microsoft stock 10 years ago would now have about $69,000 worth."
Compare that to Apple and tell me Microsoft is not in decline.
Major companies values are forever changing and swapping places with one another. Just a look at your major supermarkets proves that.
