How is the TI-83 still a thing? iPod is superior in every way: CPU display size and color, flexibility, cost (well, if they produced a last-gen version for the down market, it would be)
Also, don't underestimate the value of a UI and hardware keyboard centered around a specific workflow. Calculators are almost the opposite of a tablet/phone, computers specialized to programming and user input, with communication and content consumption as an afterthought at most.
