A mind-boggling set of functionality in one 'product' And yeah I know the licensing only makes up a fraction of the TCO of software, but still, the fact that the functionality you can get from one distro that frankly is way better than a lot the stuff that would cost you $100K + from MS (ISA? Sharepoint? MCMS?, please...) has a lot of implications for the future of commercial software.
Ok, this isn't rocket science - why am I now realizing/writing about this. Well I'm not. But I was chatting with my SoC mentor Rok Zlender, who's from Slovenia, and he mentioned that all his CS program at uni uses is Windows. Which is exactly the case at UWI. For some reason, some of the countries that could probably benefit from the nature of FOSS are the ones where MS is firmly entrenched.
Now I'm not being cyniclal - I think MS is doing a good thing with its low-price desktop suites for developing countries and programmes like Microsoft Unlimited Potential and its initiatives in Africa, but it would be really good to see people developing hard skills in software development and administration using FOSS. FOSS offers the opportunity for developing countries to create a set of highly knowledgeable IT workers at a very low cost.
The main problem is, I think, that all the consulting firms in countries like ours only know how to make a profit selling licenses for software and implementing MS infrastructure. They are making their money with commercial software so there's no incentive for them to turn to anything else, regardless of whether it would benefit the country or not.
