Department of Transportation staying away from Vista?

The Chief Information Officer of the Department of Transportation has placed an “indefinite moratorium” on upgrades to Microsoft’s latest operating system and software suites. This was due to concerns over compatibility issues with the latest software that the Redmond giant has released.
The unfortunate consequence of Vista currently is that many of the products that the DOT uses are not Vista-capable yet and there have been sightings of certain security issues with IE7 and Vista. Until those are resolved, it sounds like the DOT is holding off.
