Linux -vs- Windows

I have had several people tell me they are fed-up with Microsoft Windows and asked if there in an alternative. There is, It is called Linux. Like Windows, Linux has several versions:
* Debian-based
* Slackware-based
* Pacman-based
* RPM-based
and a few others.

The following link tells about all the different versions and their main purpose: http://en.wikipedia.org/wiki/List_of_Linux_distributions

For those interested in comparing Windows & Linux, the following links are for you: http://www.computerhope.com/issues/ch000575.htm

I don't know much about Linux, I have never used it, but I know people that have and they say it a good Alternative to Windows, but not every ones "cup of tea."

I hope this helps a little and I will continue to research this, so I can give a more informed opinion. Watch for future posts on this subject.
