Too early, too little, but here's a quick overview of Distroreviews impressions.
It isn't much, but it's better than nothing on a slow day.
I was anxious to have a look at this release as it has been mentioned that this release's focus is to be a “polished” distribution. I was hopeful but not expecting the first flight (beta) to show much of this polish. As I expected, this early release of Dapper Drake looks virtually identical to 5.10 as changes in this early release is mostly concentrating on merging work from Debian unstable.
