Open source to hit $22 billion by 2010

As per this article:

Open source software’s presence will increase from approximately 10 percent of key enterprise on-premise software in 2007, to between 15 percent and 20 percent by 2010.

Why is Open Source so Disruptive?

• An ability to customize and use the software code to whatever extent required and useful, and
• Reduced dependence upon software vendor technologies, license schemes, and maintenance/support requirements.

Benefits can include:

• Reduced time and costs for development;
• Improved reliability based on massive, repeated testing and tweaking; and
• An increasingly broad base of technologies and skills that effectively further reduce the costs of development, as well as the costs of maintenance, support, and associated software requirements.
