I don't see any competition at programmable calculator's market. Why noone gets a modern SoC, connects it to a modern OLED display (but keep hardware keyboard, please), burns in basic DirectFB-based GNU userland with tons of readily available free science (not only math) and programming tools, designs an basic UI over the thing (most hard part), keeps the POSIX shell available and device completely unlocked, and starts selling the product? I do believe there are parents who would like their kid to have a good calculator to aid in the school, but don't want them to have an iOS/Android tablet (as it's more likely the kid will end up playing or using it for social networks). I mean, replace everything that sucks about graphing calculators - outdated (and seriously overpriced) hardware and limited programming and debugging functionality (if you're about to argue - please compare TI calculator to your development workstation to see what I mean), but keep the device feel generally science- rather than entertainment-oriented? In short: a handheld device with a general feel of modern programmable calculator, with (preinstalled) Maxima, Octave, PHYSICA, R, Python, Racket and so on under the hood, and without any [readily available] "app store" full of games. Or such products do exist, but I just haven't stumbled on anything like this?
