> Just curious, why would you get buttons instead of sensors?

Two things:

1. Long hair. If your hair is in the way, you have to brush it away before the sensors will correctly register your input.

2. Beanies. If you wear an acrylic beanie (due to the aforementioned long hair), there is enough capacitance detected in contact with the material to generate spurious, and unwanted, inputs.

Tactile buttons would solve both of these issues.
