You're completely missing the enterprise side of the equation, which is still a booming part of MSFTs business right now. And they are still a goliath in Enterprise (Windows Server, Exchange, SQL Server, etc).
You also speak of their 'downfall' in the past tense, as if it's already happened. They still push 90% of desktop market share, rule enterprise, rule the Office suite business, and have some nifty things going on in the entertainment side (not profitable, but nifty nonetheless).
