ELI5: Why are graphing calculators so big and bulky when they don't have anywhere near the computing power of a much thinner smart phone?

Graphing calculators aren't really bigger than they need to be. You can only make it so small while still having enough surface area to fit all the buttons. They probably *could* make them smaller, to a degree, without much change in cost of production, but people would likely find them too cramped to work with. The smaller and closer together things are, the harder they are find. There needs to be adequate spacing between the buttons to "feel right" both tactilely and visually.
