Named after an Italian dessert, Sabayon aims to be the "cutest" Linux distribution "as easy as an abacus, as fast as a Segway." It's based on Gentoo, and it supports the KDE, Gnome, LXDE and Xfce desktop environments.
38. Joli OS
Joli installs in just ten minutes and is optimized for cloud computing applicatons. Use it to breathe new life into an old PC, or you can run it alongside Windows.
A good choice for netbooks or older PCs, Peppermint is designed to work with cloud and Web apps. The name might make you think it's based on Mint, but it's not. It's actually based on Lubuntu, which of course, is based on Ubuntu.
Formerly known as Peanut Linux, aLinux is designed to be both fast and multimedia-friendly. Its graphic interface provides an easy transition for former Windows users.
At just 50MB, this distro lives up to its name Damn Small Linux (DSL). As you might expect, it's very fast and runs on older PCs, as well as fitting onto small USB drives and business card CDs.
42. Tiny Core Linux
One of the smallest Linux distros available, Tiny Core weighs in at just 10MB in its GUI version. The command line version, Micro Core, is even smaller just 6MB.
43. Puppy Linux
Small and fast, Puppy is designed to be installed on a USB thumb drive that users can take with them and boot from any PC. It takes up about 100 MB, boots in less than a minute, and runs from RAM for maximum speed.
44. Zorin OS
Unlike most Linux distributions, Zorin was designed to look and feel as much like Windows as possible only faster and without as many bugs. It's available in both free and paid verions.
45. Ylmf OS
Like Zorin, Ylmf's interface looks a lot like Windows, in this case the Windows XP classic look. Created by Chinese developers, it's available in either Chinese or English, and it's based on Ubuntu.
GoboLinux's claim to fame is that is doesn't use the Unix Filesystem Hierarchy Standard, but instead stores each program in its own sub-directory in the Program directory. That means that it's a little bit easier to use for Linux newbies or experienced Linux users who like to install applications from the original source code.
Designed to be easy to use, PCLinuxOS can be run on a Live CD or installed on a desktop or laptop. It supports seven different desktops, including KDE, Gnome, Enlightenment, XFCE, LXDE, and others.
Based on Intel's Moblin and Nokia's Maemo, MeeGo is known as a smartphone OS, but it can also be used on netbooks and other mobile devices. With Nokia moving to Windows Phone 7 for future headsets, MeeGo's future is uncertain.
Google's operating system goes by two names, which can make things confusing. Officially, "Chromium OS" is the open source version used primarily by developers, and "Chrome OS" is the name for the version of the operating system Google plans to include on netbooks for end users. And just to make things even more confusing, both projects share a name with Google's Web browser. For now, Chromium OS (the only version available for download) is really only suitable for advanced users and developers.
50. Musix GNU+Linux
As its name implies, Musix is geared for multi-media enthusiasts, particularly those involved in audio editing. It can boot from a live disk or be installed on a system.
