Like everyone else in the world we posted our glib view that many Windows users would want Vista after seeing the demo yesterday. However a well researched and explained post can be found over at WWD.
The post is focused on Windows users who are of course the audience this question pertains to, not those using Mac OSX or Linux. As we said it’s more likely to be acquired via a new PC so isn’t going to be a landslide like some earlier versions of Windows that didn’t require as much new hardware.
The ability to upgrade to Office 2007 on XP is another good point made in the article which we hadn’t thought about. Still we think most of the Vista and Office 2007 footprints will be made with new hardware.
