Ask any Windows pundit about all the different versions of Windows Vista that Microsoft offers and you’ll invariably get the same response. There are too many! Consumers are confused! It all needs to be simplified! To which I say: Be careful what you wish for. The case for reducing the number of Windows versions to one or two sounds convincing in the abstract, but the argument breaks down quickly once you start to examine the details and consider how such a change would affect the way you and I buy Windows on consumer and business PCs. For starters, would you be willing to pay 17.5% more for an entry-level PC? That's just one of the problems with this idea.
