I was 11 when I took this screenshot - Ubuntu 14.04 running on my very first (incredibly bad) PC. As I recall, I couldn't install Windows 7 without a DVD drive, and that was out of my budget :p
Pretty sure I had it riced out with the Compiz cube and everything.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I had a live linux USB with Zorin, all set up with funky compiz cube animations and stuff. The casper-rw file always kept getting corrupted though and repairing it was a pain for me back then. That thing was what got me interested in Linux over a decade ago, I think I still have an image of it somewhere...
Then the RPi came along and sealed the deal. From that point on, I've always had a linux machine, up to now where my daily driver laptop runs Linux
