Ubuntu 9.04 to 9.10 upgrade is smooth

Yesterday evening I tried to upgrade Ubuntu 9.04 to 9.10. It was a very smooth process, 1700+ packages were upgraded, some obsolete packages were removed, and after a reboot, Ubuntu 9.10 was installed without an issue. It runs smooth and all the common applications run well (Firefox, media players, OpenOffice, wine, common development tools, Samba client, etc). iBus is now included and I like it better than SCIM for Chinese input.
