Upgrading to Windows Vista has been banned by the U.S. Department of Transportation (DOT), the National Institute of Standards and Technology (NIST), the Federal Aviation Administration (FAA), technology giant Texas Instruments and other corporations and government agencies (V1, V10, V11). These organizations are evaluating their options, but overseas it's turning into a stampede to get out of Microsoft software (V15).
School districts in the U.S. are starting to move entirely to Linux rather suffer the cost of upgrading Windows. Examples are the Windsor Unified School District in Northern California and the Bexley, Ohio high school district. Schools making this move have been surprised how easy it is and how much money is saved. (V6, V8)
