After Windows XP the OS has had a significant increase in stability. This is even further improved with Windows vista, 7, 8, and 8.1. The problem with this then has been motivating people to switch to a new product. The same scenario with Office.

The difference between Microsoft and Apple has been the cash premium Apple charges for its hardware. Software business model for OS's isn't that different now. Some actually dare say Apple may withhold features to keep people on an annualized buying cycle of their devices.
