The recent report by Gartner, the State of Open Source 2008 (http://www.gartner.com/; report G00156659), as summarized on their site provides some very interesting conclusions:
1. By 2013, a majority of Linux deployments will have no real software TCO advantage over other operating systems.
2. By 2012, 90% of enterprises will use open source either direct or embedded.
3. By 2011, open source will dominate software infrastructure for cloud-based providers.
4. By 2012, software as a service (SaaS) will eclipse open source as the preferred enterprise IT cost cutting method.
