Use Arch Linux quite a while, I like the “pacman” command-line, simple and easy installing packages. Then I think about the other package managers such as deb with aptitude, rpm with yum or zypper or urpmi, how will they look like? Because of this, I tried several LiveCDs/LiveDVDs with VirtualBox: LinuxMint 13, Ubuntu 12.04, Fedora 17, OpenSUSE 12.1, Debian 6.0, CentOS 6.2, PCLinuxOS 2012.02, and Mageia 2.

I didn’t go through all the distribution thoroughly, just tried the installation, a web-browser, and the package manager.
