Okay,singing requires manipulation of your voice (diaphragm + airways. You also need to know the correct posture to keep,but its not 100% necessary).
Dancing requires manipulation of your feet, legs, hips, shoulders, arms, hands, and head. Sometimes your belly and butt as well.
Just having a sense of rhythm isn't good enough. You can bob along to a rhythm with 100% accuracy, and not be "dancing." You need to know how to move your body in a way that is rhythmically accurate and pleasing to the eye, coordinating different body parts in alternating, but synchronized patterns. It's a totally different skill set. Musicians,for example, are often very reluctant dancers.
I do think that more and more people are starting to want less intrusion by the devices in their life so I wouldn't be surprised if a true affordable dumb phone enters the market in the next few years.
