Fascinating for me is slide 13, which shows how the decision criteria for open source have changed from 2008 to 2009. Number one is lower TCO (unchanged). Access to code, which was #2 last year, has dropped to 5th rank in 2009. Now, "Superior Security" is ranked second, up from 7th place in 2008. Third rank is unchanged "Freedom from vendor lock-in" and new this year is 4th rank: "Better quality software".
So open source software is perceived as cheaper, better and more secure than proprietary alternatives. Sounds like a pretty good position to be in for any Open Source vendor.
