The saviour that was meant to be, Vista Service Pack 1, isn’t. In some cases it’s actually a performance decrease for an operating system already grinding up-to-date PCs to a halt. XP fans (for the most part) are happily using Service Pack 3, and Windows 7 (formerly known as Blackcomb) is barking at the gates (or should that be Gates?), ready for an early release in Q3 2009. Windows Vista never stood a chance.
