I am a happy Dapper user - my system is now perfectly setup to do all my daily business and to watch DVDs. I am not yet updating to Breezy, though curiosity dragged my to try out a preview release. The new upstart init daemon looks promising - I only tried the live cd and didn't play much with it.
So my shell will not seen an "apt-get dist-upgrade" in the near future.
Ubuntu rocks - Already waiting to see how The Feisty Fawn will look.
