Congrats on the latest Gutsy release. I've been away from Ubuntu for some time, and have (in the past 24 hours) installed both Fesity and Gutsy tribe5. While there were some bugs to be expected with pre-release software, one thing that stuck out was the incredible speed of apt on Gutsy. This typically isn't the type of thing that I would notice, but after the updates finished downloading they were installed almost immediately. Very nice.
