I’m amazed you actually think that Apple’s mice don’t have any way to scroll.
They have touch area where the scroll wheel would normally be, that works extremely well.
It'll scroll (well, perform a swipe action, which usually translates into a scroll, except the wrong way around), but it's not the physical knob normal mice have.
I also find the scroll response rather unpredictable. I usually love touch gestures, I'm even considering getting one of those Apple touchpads for my Linux machine, but the scroll area on the tiny curved mouse surface isn't intuitive to me.
Of course Apple's mice don't have a physical knob, so that approach doesn't work, but knobs and mice can work outside of the Apple sphere.
On touch screens, you can probably make them work by tapping the knob and popping up a slider to control the value. Lets you use knobs to maintain an overview while exposing usable controls for modifications.
