There are pro's and con's for both proprietary and open source software. It is a question of the right tool for the job. Open source is not necessarily free! I see great opportunities for levelling the playing fields in the South African IT industry, and believe that open source will enable small IT companies in South Africa to provide win-win solutions. Below are some of the key links I track regarding open source software. Note I have also included some Freeware software (free to use but source code not distributed so it is free to use but not free to modify). Most of the software below runs on both Windows and Linux as well as other operating systems.... why tie yourself to one OS? Interoperability is really key if you want the freedom to later be able to change operating systems. Corporate and Government users should be aware though that they should always vet the use of any software with their CIO's before use. Also beware of OpenCore software where very basic core functionality is available as FOSS but everything else is a commercial release.

Google Documents - now has a distinct MS Office 2003 look to it and the latest update has added very powerful real-time collaboration features. It's free to use and just needs a browser to access it. Note this is not secure enough for governments as was seen recently when Google launched a separate Google Apps for Government in the US where special agreements include keeping the data within the geographic boundaries of the USA. The Google Documents folder has now transformed into a Google Drive that will allow synchronising of folders from a Windows or Mac computer (and Linux to follow... eventually).
