This is a discussion on Window Vista vs Window 7 within the Windows 7 , Windows Vista Support forums, part of the Tech Support Forum category. What are the extra added features added in window 7 as compared to window vista
My observation is that what is not in Win 7 that was in Vista is the greatest positive. More stable, less bothersom ( do you want to do what you just said you wanted to do . . do you really, really want to do it ) much lighter on resources, more nimble.
A comparison of XP to ME comes immediately to mind.
