Microsoft could face legal action over the Vista name. Microsoft recently chose the Vista name for the version of the Windows OS previously code-named Longhorn, and this has prompted John Wall, chief executive officer of Vista (a Redmond, Washington-based custom application and services provider) to consider a potential case against Microsoft.

"If people call it Windows Vista, that's not a problem," John Wall says. "If people call it 'Vista,' that confuses it with our business and what we do."
Wall claims that Vista will be analyzing traffic to its Web site to see what effect the "Windows Vista" name may have on visitors, and on business.
