I have recently bought a window vista ultimate and was pretty mad once i installed the product.Although there lots of cool new features added such as the new 3d screening but the bad thing is that most of my printers and other usb connected devices don't work due to the fact that it's too "old"(all products from 2005).it seems that vista has not yet updated 2005 and older products so if your computer is used for business i suggest you wait few months or until they fix the bugs until purchasing vista
