New version of AntiX Linus released
One of the best reasons for using Linux is that it can make an old computer useful again. The light versions of Linux use the latest version of the operating system and have the applications you need, but use window managers that run faster on an old computer than the latest version of Windows or Ubuntu.
My wife has given me an old IBM Thinkpad 600X for my birthday (256 MB of memory, 12 GB hard drive) and I've already installed my favorite light Linux distro, AntiX Linux (the light version of Mepis Linux). A new version was just released today. As with past versions of AntiX, it appears to have many more applications right 'out of the box' than other light distros, and installing it was fast and easy.
