Why don't schools make Mac-apps?

Mac is still gaining ground there I suppose. I suggest that you be the one to make it happen – and make all program strings separate to ease portability between languages!

There are lots of educational apps for the mac here though…

Apple’s share/% of the personal computer market is no where near Windows so many developers opt for greater return on investment in R&D and don’t develop for Mac. Saves the company money, or so they think.

True. Most of the world is still on Windows. Some schools do have Mac apps here in the US, but those are few and far between. Seems like it may not matter for too much longer, if web applications keep the path they’re headed on.

Web apps is where some folks are banking right now. I work for a unified school district and the only thing I can tell you is that it makes sense to move to web based solutions, but it should only be done if the school has the resources to replace computers every 3 years, five at most. Web solutions can be resource or processor heavy. We are currently experiencing a lag on computers that are beyond the 4th year mark. It does not help that they are only running with 256MB of Ram 512MB at most.
