re: 3 Reasons Linux Doesn't Star In U.S. Schools
kmcowan, you should know that I'm a Linux user myself, and I was trying to parse out why--why, for heavens sake!--open-source isn't more common in U.S. education. To your point, discounts from MS and Apple aren't the reason people don't use free software. Rather, the discounts are an answer to this competitive threat (growing out of an effort to stave off illegal copies).
I completely agree with you, by the way, about the inherent benefits of "greater security, reliability and stability." So, why isn't Linux more common in K-12? If I had to pick one thing, it'd be lack of familiarity, followed by the understandably fractured nature of this platform, which has lots of flavors (one of reasons I love it).
Another excellent point raised in the comments above concerns the impact of browsers and cloud services. Once everything happens using a browser front-end, switching OS horses becomes a much more trivial issue. --Ellis Booker
