Ubuntu

Ubuntu is by far my most favorite linux distro.

It is developed with the user in mind. With that said, they gear themselves toward a wide range of users, not just the advanced tech geeks like with other distros.

Info courtesy of Ubuntu:

Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need – a web browser, presentation, document and spreadsheet software, instant messaging and much more.
