The only reason Microsoft are growing is because they have a monopoly in a market that is still growing, hence they grow as the market grows. Outside of their monopoly everything the Microsoft does is a total failure. For example:
Windows mobile - Market share dropped from 65% to 15%.
Xbox - They're still down about $4billion, the current console has a massive failure rate and at the current rate of sales the PS3 is going to overtake the 360 leaving them in last place and with a massive loss fortune.
Search - I think they're down about $14billion and can't get most people to switch from Google even if they pay them. They've have been in an even worse state if they'd managed to buy Yahoo but fortunately their total inability to execute saved them on that occasion.
Zune - No impact on the market.
Kin - LOL?
Investors look at the company and see that everything they do is a failure so nobody has any confidence in them. Contrast this with Apple:
iPod - Massive success
iPhone - Massive success
iPad - Massive success
Mac - sales growing and setting new records each quarter.
This is why Apple's share price is through the roof while Microsoft's has been static for the past decade. Microsoft either don't know what the customer wants or are too stubborn to give it to them and instead want to continue to force unwanted products on the market through their monopoly. Look at XP - most corporations still want an efficient OS with a consistent interface but Microsoft want to force them to adopt a new OS which adds nothing but flashy visuals and an inferior interface. Why can't they give the customers what they want and put the XP interface into Windows 7 as a second desktop environment thus saving companies a fortune on training and pleasing users who prefer XP? They could easily do this but it's just not they way they do business and instead of listening to what the customer wants Microsoft wants to tell the customer what to do.
At some point Microsoft will face a challenge to their OS monopoly and at that time their inability to deliver desirable products will be the end of them. With the way the company is run things can only go downhill for Microsoft and that's why their share price shows no sign of growth.
Microsoft certainty aren't tanking as the summary said but it's only a matter of time before they are.
