Does that sound like it needs a grand machine to meet minimum requirements? Microsoft also looks at existing hardwares when developing any version of Windows knowing that their product has to be able to work on older systems in order to be able to get people to upgrade to it.

How many are in a rush to upgrade to Vista? will be another item. When 98 came out many waited until ME came out to go with 98SE. Vista will have 5 versions over XP's three current being Pro, Home, and 64bit. Most home users will probably choose the Basic or Premium versions since the other three are directed for businees and commercial applications there. Tell your co-worker to get the facts first. Hopefully this helps you out a little there.
