Don't Fear the Penguin: A Newbie's Guide to Linux
Getting started with Linux can be an intimidating task, particularly for people who have never tried any operating system besides Windows. In truth, however, very little about Linux is actually difficult to use. It's simply a different OS, with its own approach to doing things. Once you learn your way around a Linux desktop, you're likely to find that it's no more challenging to work with than Windows or Mac OS.
In this guide I'll focus on Ubuntu, the most popular Linux distribution today. But Ubuntu is just one of many different flavors of Linux. Literally hundreds of distributions are out there, appealing to a broad range of users--from teachers and programmers to musicians and hackers. Ubuntu is the most popular distribution because it's easier to install and configure than most others; it even comes in a few different versions, including Edubuntu and Kubuntu. If you happen to be running a different distribution, such as Fedora or OpenSUSE, you'll likely find that much of this guide still pertains to you.
