I've poked around for some publication data and found none. Some other indicators that I found: a medium-sized (15,000 student) research-focussed university in the US will typically have an intro logic class once/year with 100 students in it. A larger (50,000 student) university will typically have three intro logic classes three time/year with 200 students in them. This seems to vary widely though, depending on programme requirements. Also, many of the big logic textbooks are into their 5th, 10th, 12th editions. Part of this is, of course, to undermine the used market. But the market appears very, very crowded. So presumably the ones that go into multiple editions sell well too. > > I'm just not sure how to tap that particular market. > > > I think that is going to be tough with a Mac-only product. Yeah, that's what concerns me. Anecdotal evidence suggests Macs have a large percentage of the education market; maybe close to 50%. But I guess since Macs can run Windows software but not vice-versa, it will be difficult going with a Mac-only solution.
