An excerpt from the site:
"LindowsOS is a modern and affordable operating system for Pentium based computers. LindowsOS, due out 1st Quarter of 2002, will have the unique ability to run Linux® software titles as well as many popular Microsoft® Windows® software titles giving computer owners and organizations of all sizes new options on the desktop. "
