You're not wrong about the software being bad, but the actual UX involves physical buttons and dials. Haptics are very important unless you photograph completely static scenes from heavy tripods.
Having a Nikon and being able to shift shutter speed / aperture with a dial is very important.
You can kind of think of this as a remote control. Yes you can have a touchscreen as the only interface for a remote control, but you always have to look down at it to use it.
On my remote I can control volume and channel without looking at it.
