Forrester's latest set of consumer adoption data allows for a first look at Vista adoption in the first two months following its January release. On the whole, Vista early adopters tend to be more engaged with their PCs than XP users, especially in advanced usage cases like gaming and digital media. The Vista adoption picture is still very blurry — due to confounding variables such as consumer self-selection, natural PC replacement cycles, and shifting trends in PC consumer behavior. Market researchers should watch the next few cycles of Vista adoption data before making firm conclusions about Vista's impact on the PC market.
