Courageous sixth-grade teacher built a 70 computer lab for children equipped with Ubuntu (cost 0$)

Ubuntu is widely known and used for its core values, such as freedom, tight security, stability, ease of use, etc, nevertheless, in our economic world money are important, fact that adds another important quality to Ubuntu, that is, Ubuntu is free and open-source and can be used by anyone without needing money.

The story of Robert Litt is both simple and interesting; Robert is a sixth-grade teacher "faced" with problems common for low-financed/specials schools, that lack proper/normal school-specific equipment, vital for children seeking to mainly learn basics about computers (resizing pictures, modifying simplistic websites, creating spreadsheets, etc).

Hit by this problem, triggered in Robert a serious "adventure" focused on gathering computers for a classroom.

First piece of the adventure was finding the actual computers, thus, in 2007, Robert acquired 18 computers via donations, action followed by installing an operating system on them, in order to make the computers usable.

The at-that-moment difficulty was the installed-into-the-computers proprietary OSes, full of viruses, crashes, slow speed, etc, basically, an unproductive environment.

Obviously, buying new proprietary OSes would have been impossible (due to the 0$ budget), nevertheless, by searching an alternative, the courageous teacher was hit by a gold mine, Linux (Ubuntu), a free open-source operating system with immediate results (working computers, increased speed, etc).

Robert didn't stop for a moment, continuing his adventure to bring and equip computers with Linux for (smaller) human beings, accepting and putting to use low-spec machines (featuring less than 1GB RAM) via his personal exciting discovery, "many computers people say are broken are actually experiencing software problems", issues resolved with the help of various Linux communities, ubuntu.com and the open communities across the web.
