The folks who suggest using GNU/Linux costs more obviously can’t do the maths. Here’s an example.“The Slovak Republicâ€™s Bureau of Statistics has used PCs running Ubuntu Linux for recording votes in the countryâ€™s municipal election on 29 November. Using open source saves money, says Å tefan TÃ³th, Director GeneÅ•al of Informatics Section at the agency. For the bureauâ€™s IT system administrators, Ubuntu proves easier to maintain and configure, and the software also withstands malware attacks better than the proprietary alternative, director TÃ³th confirms.” For the last municipal election in Slovakia, the government recorded the votes on PCs that were essentially thin clients of a central web-application. They put GNU/Linux on those PCs although they could have used that other OS and they found they saved money. The PCs are easy to manage thanks to FLOSS package-management. They were in total control of the PCs because it’s FLOSS, not code designed by some corporate salesmen, but folks who make software that works for the user. That’s been my experience in schools. That’s the experience of other folks who use GNU/Linux in the real world.
I recommend Debian GNU/Linux rather than Ubuntu GNU/Linux but it’s still GNU/Linux.
