I've been running the recently released Deluxe Edition of Xandros Desktop OS for the past week. Xandros 3 has proven to be all that I hoped for, and more. This release should prove a good fit for many, combining the ease of use and elegant good looks that Xandros brings to the table with the underlying power and stability of Debian.
The one word that pops up in my mind most often when I think of my experience with Xandros 3.0 Deluxe is elegance. Power and polish in harmony. It won't be the "just right" distro for some, but for a whole lot of others it just might be the one that leads them from the Land of Oppressive Proprietary Software to the Land of Linux and Freedom.
The installation is the best I've seen. Xandros Desktop OS 3 gets high marks from me for correctly configuring the built-in wireless card and the display, both without any assistance whatsoever from me. Even the installation screens look as polished as any I've ever seen.
