Interesting post about digital vs. mechanical buttons:
"Sometime about 2-3 years ago, the saturated consumer electronics
industry, hungry for new but matured technology, has been exploring
what we designers call “static” buttons. These “static” buttons are
essentially non-mechanical (ie non-moving) and use electronic
circuitry as a means to detect triggering contact.
I am starting to feel such non-mechanical buttons actually reduce the
user experience rather than enhance it. Often because these static
buttons are not used in a correct context and it lacks the most
important thing a tactile and haptic feedback."
