The first impression I got when I visited the Ubuntu website at http://www.ubuntulinux.org/ was that the developers and the community are totally committed to their project. The whole first page explains the groups vision and mission. One bold line jumped out at me "Ubuntu will always be free of charge, and there is no extra fee for the enterprise edition" - Ubuntu Site. I took a look at the screenshots and it looks to be a very nice OS. I haven't had the pleasure of trying it out yet, but I did order my free copies from the site. All you have to do is visit here: http://shipit.ubuntulinux.org/ . The greatest thing is that the discs and the shipping is free.
