I have been using Ubuntu for about a year now and it has been an incredible ride. It is the first distribution that I have real admiration for, well FEDORA too. But this distribution really has their stuff together. Give it a try, its free!!
Ubuntu is a complete Linux-based operating system, freely available with both community and professional support.
Ubuntu will always be free of charge, and there is no extra fee for the "enterprise edition", we make our very best work available to everyone on the same Free terms.
Ubuntu comes with full commercial support from hundreds of companies around the world. Ubuntu is released regularly and predictably; a new release is made every six months. Each release is supported with free security updates and fixes for at least 18 months.
Ubuntu includes the very best in translations and accessibility infrastructure (the Rosetta system) that the Free Software community has to offer, to make Ubuntu usable by as many people as possible. We collaborate as widely as possible on bug fixing and code sharing.
Ubuntu is entirely committed to the principles of free software development; we encourage people to use free and open source software, improve it and pass it on.
