At meals, I found myself in enthusiastic conversations with others who were telling me how they've found OpenOffice.org and other free or open source software to be better than the commercial software they or their organizations had been using.
The conclusions don't seem strange; I might have expected that from people focused on technology, and they match much of my experience. What surprised me and pointed out my naiveté was seeing that excitement about free and open source software from a group of people focused simply on using software to be effective in their regular work.
I was reminded of this today by seeing Solveig Haugland's posting on Vista and Office 2007.
By the way, for those of you not sure where to find good open source software, check out Ubuntu, SourceForge.net and the GNU project for starters.
