The new Windows Vista system is system-resource hungry, making your Core 2 Duo PC run like a PDA. The program itself isn’t cheap either, those who can’t afford it either go for illegal copies, or choose not to upgrade at all; but you got to give it to them, the new user interface (UI) does look good. Today we came across a set of graphics that were in the design pool (and Longhorn) during the Vista development process, these are the screens, wallpapers, icons and product packages that never made it to the final product. Perhaps they can “inspire” some fans to skin their Vista later. We’ve got a lot more pics after the jump.
