Buttons and scroll wheels cost more than touchscreens at this point… 90s me wanted touchscreens on everything, and me since maybe 2015? has been firmly “bring back buttons”
…whenever they started replacing useful things that SHOILD be buttons always (car) with touch things. Absolutely not bueno.
It’s not that they cost MORE, they can be sub-cent per unit if you buy enough of them:

For just the part yes. Board design, programming, and manufacture costs increase with more components.
Of course they cost MORE than putting all their functions on a tiny touch screen that’s already gonna be on the device!
Beyond manufacturing the device to be able to use separate physical moving pieces, you’ve also got costs supporting pieces that break in warranty, units damaged in shipping due to moving parts being tossed around, etc.
