I began using Linux whilst still working with XP most of the time. That was back in late 2006 with Ubuntu 6.10

Back then Ubuntu was much less automated than Ubuntu 9.04 and Ubuntu 9.10 which we have today and was a much steeper learning curve with a lot of work still necessary in the Terminal

Yes the latest releases of Ubuntu/Mint etc. are a pleasurable experience indeed but if you want to try out Ubuntu 6.10 it is still possible by modifying the repositories although Ubuntu 6.10 is no longer supported
Ubuntu 6.10 Download

Once installed you need to replace the repositories to obtain any updates that were available before support ceased THIS IS IMPORTANT
Open the Terminal and submit the following command
sudo gedit /etc/apt/sources.list
Delete all the repositories and replace them with these
deb http://old-releases.ubuntu.com/ubuntu/ edgy main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy main restricted
deb http://old-releases.ubuntu.com/ubuntu/ edgy-updates main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu/ edgy universe
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy universe
deb http://old-releases.ubuntu.com/ubuntu/ edgy-backports main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy-backports main restricted universe multiverse
Once replaced save then in the Terminal
sudo apt-get update
After you have done this updates will become available. There is no Wubi installer for Ubuntu 6.10 so grab a spare Hard Drive or install it on a virtual machine I recommend VirtualBox

Give it a go as it will increase your knowledge because things are not so automated.
