Canonical is working hard these days to redesign the Ubuntu installer (also known as Ubiquity) into something a little more in tune with our times. We've already told you in our latest report on Ubuntu 9.10 (Karmic Koala) Alpha 4 that Ubiquity has now a "Quit" button during all the installation steps, so you can quit the installer at any time. Moreover, the time zone selection items have been changed a little to reflect the region/zone only, and not the city.
