The US Department of Transportation (DOT) and the Federal Aviation Administration (FAA) have banned Vista, IE7, and Office 2007 from 60,000 desktops. That's a major event, especially since Vista is currently hovering at about 1 percent market share. It just makes sense - they can't justify spending taxpayer money on these unnecessary changes. And it's not just the US, Cape Town is switching as well. I have to agree, the first agency I see announcing an full blown Vista upgrade is going to get printed.
A bad death spiral - it's too hard to upgrade, Dell is selling machines without it, there's no one standing in line to buy it, and Google is now raging. Who would of thought that concern for the environment would kill a giant?
