Ubuntu Linux has been installed on Maquina 02 in the main UTC Parras computer lab.
I did a bunch of searching for spanish language articles and docs arguing for Linux. The best I could find is here, debunking 15 myths about Linux: [1]
This google-translated version of this page will also be useful for English-language readers: [2] The article talks about how Linux has helped nations such as India and Argentina become software exporters, it talks about how Linux is more secure, and easier and safer to administer. It mentions the use of open standards, etc., etc. (there are 15 myths debunked)
And, how else did I find this document but Wikipedia. Check out the Spanish language article on Linux. I'm sure it will be useful for spanish-speaking people getting started with Linux: [3]
On the question of Suse vs. Ubuntu: Suse might be chosen by engineers because of the many GUI admin tools that come preinstalled with it, and because it's "old hat" (not red hat), as in, it's been around for a very long time.
But from the way Ubuntu is presented on their website, you can see
it's tailored to users transitioning from Windows, or who are new to computers. It's easy to install, free, and has an organized support community. Whereas the company that puts out Suse makes money off of providing support and services. Also, even though Ubuntu is a newer package, it is based on the most popular Linux distribution, Debian, which has been around for a long time, and for a long time to come. Most key, I think, in your cas,e is the difference in storage requirements for the respective Linux packages: Ubuntu installs off of one CD, and requires minimal hard drive space.
