Quoting from the Altiris official announcement:
Altiris, Inc., a pioneer of service-oriented management solutions, today announced that, according to a recent survey commissioned by Altiris, 41 percent of IT organizations plan to deploy virtualization in client PC environments. The survey also revealed that the top two benefits of virtualization technologies are hardware optimization and reducing the cost of deploying and maintaining applications.
While 41 percent of respondents plan to deploy client PC virtualization, the survey of more than 550 IT professionals found that only 8 percent of all individuals surveyed have currently deployed application virtualization technologies in their client environment. In comparison, 71 percent of those surveyed have deployed or plan to deploy virtualization in their server environment.
