When Vista was released, and the first reviews started to trickle in, it became apparent that Vista was a massive release - not only in terms of money spent on it by Microsoft and the amount of promotion, but also the operating system itself. It was
huge, and it felt as such too. Despite what many have been saying the past year, Vista is, in fact, much more than just XP with a new theme. Basically every framework and feature has been rewritten, lots of new ones have been added, and, according to some, the process of modularisation has
started with Vista (and Server 2008). It may come as no surprise that all these changes resulted in a whole boatload of bugs and breakage, which led many people to conclude that Vista was simply not as "done" as it should have been when released. Steve Ballmer confirmed these sentiments in a speech at Microsoft's Most Valuable Professionals conference in Seattle.
