I'm not too sad to see old calculators go -- I'm just hoping we'll get something like python notebooks on smart phones used in the classroom. Might have some problems with the networking... maybe there's a marked for an android pad that doesn't have any wireless hw?
In Norway those Casio calculators were also approved for use at the college level -- but they were stupidly banned, because you could flash the rom, and store all sorts of useful things on them. Really stupid IMNHO, because if you can solve the (college level/sen. high school level) exam with the help of some utility or other -- or just a large book -- the exam is probably structured very poorly.
There was an initiative to move to "open book exams" -- where you were allowed to basically bring any books/notes you wanted. I think it was great -- the questions were a little harder -- and you still had to know the subject matter or you'd run out of time before completing -- but I think it encouraged better tests than when you could essentially administer a glorified spelling test for any subject.
