That poorly organized companies that grow up like mushrooms, surfing on some "new" wave of techhnologies, sooner o later fals down when that wave starts loosing its momentuma, is nothing new, and certainly not more typical in the IT sector than in any other sector.
You may argue that MS and Nokia both are mushrooms, but the point is that Nokia is the archeotypical example of the opposite. MS have shown by now that they will survive.
Another point is that neither MS or Nokia need to revolutionize anything. They only need to do what they are good at.
