... and your not that technical... then Mint is for you!
It is based on the Ubuntu distro, but with all the extra's most people need added in their desktop setup (eg. media codecs etc.)
One of the problems for non technical people using Linux has been that "It's great, BUT you need to add x,y, and z" to make it work for you.
Mint solves this by putting all those common extra's into one easy package.
I've used Ubuntu for the last few years and really enjoyed it. Mint is Ubuntu with the bits I normally add manually already there. It is a joy!
So if you want to miss the and Adobe taxes this maybe the answer!
You also get Open Office and all the other Linux goodies in one hit.
note: Open office will read and write Word, Excel and Powerpoint files.
The GIMP (as reviewed by Rick) is included; so your photo editing needs are also sorted.
There are a total of 41 graphics apps including image viewers, scanners, converters and editors.
