According to Evan Dandrea of Canonical, Ubiquity in Ubuntu 10.10 will have a completely revamped and more-beginner-friendly interface. Ubiquity is the name for the installer used in Ubuntu.

This is what Evan said to Softpedia:

While the visual changes form a large portion of the work, some major pieces infrastructure will be added or changed to support things like running installation tasks in parallel and the Geonames place name service.

A big change in the new Ubiquity, other than the interface, is the introduction of “paralleling  task” functionality. What this will do is that the installation process will be divided into  parallel  processes so that when the user is entering information like time zone, name etc., the  installation  can continue in the background. This will speed up the  installation  process.

Here are some screenshots of the new Ubiquity for Ubuntu 10.10:

This is the first step of the new installer. Here you can specify if you want to download updates from the internet during the  installation  and if you want non-open-source software like Flash, audio and video codecs etc. are to be installed.

This is the Hard Disk partitioner. You can specify the partition or the amount of space to be used for the Ubuntu installation.

This is the final step of the installation. You can specify your username, password etc. here. An option to take your picture with a webcam will also be included in time for Ubuntu 10.10.
