In a report sure to make its customers glad they pay so much for consulting services, Gartner analysts went way out on a limb and said that Microsoft will miss its target shipping date for Windows Vista by one quarter. The analysts also said that “Microsoft can’t accurately predict [shipping dates] more than a few months out.” That last statement is probably fair, but if Microsoft can’t, how can Gartner?
Not to mention that Gartner has a really lousy track record with its predictions.

As you’ve mentioned before, I hope Microsoft takes their time with Vista. XP is stable and solid, and for now I’m very happy with it. This fact buys Microsoft time in the mind of consumers, not to mention a solid first release might buy back a little goodwill from the haters.
