Is Windows Vista the biggest PR failure in Microsoft's history? I don't remember the criticism being this bad a year after XP was launched, nor any of its predecessors. Of course, slagging off Microsoft's latest operating system launch is nothing new, but according to over 3,000 people who answered our recent poll, the disapproval has reached new extremes. Twice as many of those who responded would rather have XP installed on their new PC or laptop than Vista.
