I have taken the plunge back in 1994 and installed Slackware Linux alongside Win3.1 on a PC that sported a shiny new 3AMD 386DX/40 CPU, 4MB RAM, a Trident video card with 1MB VRAM and a 420MB IDE hard disk. It was quite an experience to install but it was fun to learn something new. Since then been a Slackware user for nearly 10 years then moved to Fedora then Debian. It was a lot of work but got a running Linux system with some effort and searching for answers to many common problems with drivers and compiling stuff.
Nowadays I use Linux at home and was shown to be quite rock solid and gets the work done!
