costs and flexibility drive company to open source
A survey conducted by IT consulting firm Optaros and InformationWeek magazine shows that American companies and government organizations are saving millions of dollars with open source software. Conducted in September 2005, the survey is based on responses collected from over 500 companies, government agencies, and organizations. According to the collected data, approximately 87 percent of American organizations use open source software within their technology infrastructure.
Add this to my bet: In fact a lot of companies are trying open source and never go back to proprietary alternatives, or at least : less company go back than Microsoft expectations. That’s why Microsoft has started a FUD survey like ‘Get the Facts’ campaign…vendor locking won’t stop customer to go away.
