Swift Linux with Taylor Swift
This is a light weight, Debian Derivative for old computers (and new) came from Mepis base.
It is pretty good but slow to (necessity if one is having low RAM) boot up.
Gets the hang of using Linux with a bottom up approach.
One need to configure Network manually which is nice thing if you have no Ethernet.
It has libreOffice.
When you get to the home page one can get images of Taylor Swift, in plenty.
At start up it plays a tune of Taylor Swift, which is cool.
Lot of instruction available (how to configure Network for example).
if you need to learn Linux on a bottom up approach with a Live CD this what you should try.
