Not really. Remember there are lots of people out there who are completely ignorant of anything outside of Windows. Their entire computing world revolves around it. Over the years they've learned a few tricks, they might know how to setup a printer or share a network drive, maybe they can even reinstall an OS by themselves. These people are basically paying Microsoft a premium for a familiar Windows experience. The value of this experience is their own choice to make. There is also a large industry of MSCE/MSCP/etc types who have built their careers on Microsoft products. For those people a new version of Windows that isn't immediately repulsive to consumers is money in the bank. In both cases the actual quality of the OS isn't relevant. It's all about predictability, familiarity, comfort, backwards compatibility, etc. Windows 7 is closer to what people actually want than Vista was.
