Numworks: open-source, Python-compatible handheld graphing calculator
It's always amazed me how, in 2018, TI calculators with software and hardware from 10 years ago still cost $100+ dollars [0] and command a near monopoly in US secondary schools (which, I suppose, is why they still cost that much). For that price you can get a significantly more powerful and functional mobile phone [1] (see 24K of ram vs. 2GB, 96x64 screen vs. 720 x 1280)!The space needs competition, and I hope Numworks gives TI a run for their money (the calculator is even allowed on the big standard exams), but schools are so standardized on TI calculators (and generally slow-moving) that change will be hard. Casio has also tried to break into this space with significantly cheaper calculators (which are also allowed on standardized exams), but they have failed to gain significant traction so far.A relevant XKCD (of course): https://xkcd.com/768/A related piece of journalism: https://wapo.st/1Cl0Vyf[0]: https://www.amazon.com/dp/B0001EMM0G/[1]: https://www.amazon.com/dp/B01H2E0KVA/
