Re: What was your start with Linux, and then Ubuntu?
Pure curiosity got me started. I saw a magazine in a small-town supermarket with a free ISO of Ubuntu 7.04. After a lot of agonising over whether I'd destroy everything, I installed it alongside Windows without difficulty. Two or three days later, I joined the forums.
Later on, I played with other distros, such as Fedora, Puppy, Debian and SalixOS. I even had an openSolaris liveCD at one point. However, Ubuntu and its flavours has remained my main OS throughout.
Please, people, remember to BACKUP before you install that new system. Same if you're upgrading.
