FSF-approved Trisquel Linux shows free software can stand on its own merits
Trisquel, however, is definitely worth a closer look. It's Ubuntu-based and ships with an excellent (and familiar) group of core apps - Firefox, Evolution, Pidgin, Transmission, OpenOffice, GIMP, Brasero, and several others - Elisa media center is even included. A liveUSB disk creator is also provided so you can easily roll your own portable Trisquel remaster. As per the FSF mandate, everything in the ISO is 100% free.
The distribution just reached version 3.0. A light version is also in the works and is set to drop in a few days. It will feature the XFCE desktop environment and lightweight apps like Epiphany, Sylpheed, and Abiword.
Even if you're not an adamant FOSS advocate, Trisquel is a solid Linux distribution and well worth taking for a test drive.
