Like Daishiman, I'm also from Argentina, and I think his point is that Macs are prohibitively expensive here (more than in say the US, here they are hard to buy, expensive, and you pay a lot in taxes), so using Macs for a program meant to teach & reach lots of kids doesn't make a lot of sense. It's not about the OS or the computer type, but about the cost and access to repairs when they break down: you must keep the costs low or the whole program will become unfeasible.
