Bruce Perens was one of the keynote speakers at the 2012 Linux.conf.au conference held in Ballarat, Australia January 16-20, 2012. I really enjoyed his presentation so I'm sharing it below. The linux.conf.au folks have posted videos for all of their presentations to their YouTube channel. I downloaded all of them and posted them to an archive.org LCA2012 page. They are also available in ogg format.

For our Ubuntu fans as well as those who just want to learn about the upcoming release, I found this on youtube. I was hoping for HTML5 playback option, but this seems to be Flash only. The review was done from a recent release candidate that I believe will be the final release due out this Thursday. I still prefer KDE myself. :)
