There are more and more companies adopting open source solutions in favor of proprietary software due to the cost savings they can reap, although perhaps not enough. Today, I noticed this release from IBM about Italian food company Gruppo Amadori rolling out Red Hat Enterprise Linux with desktops running IBM software, much of which is free, and some of which has open source roots.
About 1,000 of the company's 6,000 employees use computers and will move to Red Hat's platform and IBM Lotus Symphony--a free software suite with long-standing open source roots, although it's not developed as open source any longer. The company will also switch from Microsoft Exchange to an IBM Lotus Notes and Domino environment hosted on Red Hat Enterprise Linux. This is the type of solution that many other companies should look into.
