a screenshot of "linux" is a complete misnomer. Even a screenshot of a given distribution makes me fall on the floor laughing.
Why do I use slackware? It has no screenshots section of it's website.
All other distros tend to have screenshots, and GUESS WHAT, THEY ALL LOOK THE SAME.
Because it's not a screenshot of the distribution at all, it's a screenshot OF KDE. (or GNOME).
If you want to pick an OS based on a screenshot, use windows.
edit: just for good measure have an unhelpful screenshot
