The average user doesnt need windows. Whichever version you care to discuss. But they have it because its the ubiquitous option. Market saturation of Vista will take about 2 years to hit that magic 20% mark, but once that happens, most businesses, homes and institutions will upgrade too... not because they 'need' it, but because its what everyone uses (and XP wont be sold any longer, and they are too scared to try Linux or OSX).
