My laptop is a 64-bit system from last year. It's graphic card is not supported in the 64-bit (ATI). It is the one that received additional eye candy from a fresh install of the Release candidate.
The desktop is from 2003 has a 1.67 GHz i686 CPU and an integrated graphics card. No visuals changed when I used sudo do-release-upgrade to force it to use the release candidate.
Ubuntu.com is now changed so it gives 8.10.
