Looks like you're in good company if you have Vista issues; senior MS execs are having the same ones:

It turns out that Mike is clearly not a naïf. He’s Mike Nash, a Microsoft vice president who oversees Windows product management. And Jon, who is dismayed to learn that the drivers he needs don’t exist? That’s Jon A. Shirley, a Microsoft board member and former president and chief operating officer. And Steven, who reports that missing drivers are anything but exceptional, is in a good position to know: he’s Steven Sinofsky, the company’s senior vice president responsible for Windows.

I've seen this problem before, although I'm surprised it happened at cash-flush Microsoft. Back when ObjectShare was running out of steam, VisualWorks 5i was in the release pipeline. We had a particularly bad quarter, and management wanted some positive news - any positive news. What did they latch on? Why, a product launch, of course! Was it ready? Heck no, and everyone knew it, from engineering through technical sales (which was me, at the time). Still, quarterly results demanded that we do something, so off it went - never mind the tremendous support problem that bought us and our customers.

It wasn't until the 5i.2 release (from Cincom, after the purchase) that we had a stabilized 5i product line. What does that have to do with Vista? Well, from what I can tell, it was rushed out early (never mind the lateness from public pronouncement standpoint). Why did they go ahead with the release, when they knew full well that it wasn't ready? One hopes that it was just embarrassment over the lateness, because the other potential answers would be a sign of some fairly deep issues that we don't know about yet. Combining this kind of boneheaded release with the deeply stupid desire to buy Yahoo doesn't say anything good about Microsoft's decision making process, that's for sure...
