Interesting to note that bzr got close to mercurial in the votes in spite of this being bzr version 1. Version 2 is much improved in speeds (comparable to git/hg).

I would be interested to know about other's impressions of bazaar and why most people seem to share the same sentiment towards it as those at pycon that year
While no one said they did not want bzr chosen, no one said they did either.
The move from 1.x to 2.x brought in significant performance and memory improvements.
I am still unclear on the impact of a "branch" being the key concept in bzr as opposed to "repository" in git/hg.
Git's support on Windows has improved considerably (although I could not find a good GUI). So I rather find not much reason to use Hg!
