It's quite obvious now that most people don't want to upgrade their operating systems every few years. They just occasionally want small useful bits added to what they've already got. They don't want radical redesigns where nothing works properly any more.

And the problem Microsoft and the whole PC industry has is that people are hanging on to their PCs longer. You don't need a computer with the power to predict weather patterns just to send a few emails and surf the net. So even sales of operating systems that come with new PCs may start to fall soon..certainly in the West.

Microsoft needs a new business plan!
