Paul Thurrott published a review on the final version of Windows Vista

It's hard to put Windows Vista in perspective. On the one hand, the product has been in development for over five years, which means that Vista had one of the longest development cycles in the 20+ year history of Windows. Paradoxically, Windows Vista is both revolutionary and evolutionary. While it includes modern OS features, such as a new hardware-based graphical user interface (GUI), Vista will also feel like familiar territory, for the most part, to anyone that's already familiar with Windows XP. The sheer size and scope of Windows Vista makes it difficult to review, to digest, and to understand. If you step back too far, it doesn't look very impressive at all: It's like XP with a spit-shine. But if you get too close, it's easy to get lost in the seemingly never-ending lists of new features. Yep, it's a major Windows version all right. And now it's complete. Let's dive in.
