For those of you interested, the latest version of Ubuntu is now available for download
here.
For those of you interested to try it out, but don't want to commit to anything or risk buggering up your partitions, you're in luck.
There is a new installation option for Windows users. Wubi allows users to install and uninstall Ubuntu like any other Windows application. It does not require a dedicated partition, nor does it affect the existing bootloader, yet users can experience a dual-boot setup almost identical to a full installation. Wubi works with a physical CD or in stand-alone mode, by downloading an appropriate ISO to install from. It can be found on the root of the CD as Wubi.exe. A full installation within a dedicated partition is still recommended, but Wubi is a great way to try Ubuntu for a few days and weeks before committing dedicated disk resources.
So get on it!
