This is another example of a company trying to price software like its a physical product.
The justification for the price is laughable; just because it contains more features than an unrelated product (for which it is not even a feasible replacement) is not going to convince someone to pay for an iPhone app 25-50x the normal going price.
I'm venturing a guess here by saying that a good portion of the market for graphing calculators is comprised of high school and college students, and I don't know of one teacher who would allow an iPhone during a calculus or physics test.
Personally I think more high-school/college tests should be given with the students using computers & the internet while taking them, since that's how the world works now. Not all tests by any means, but more than currently. But until that point, letting some students use their iphones because it's also their graphing calculator, on a test where most students don't have access to the internet and their friends and other test takers with iphones, is an invitation for cheating.
