Ah, to each their own i guess, the feedback i get from vertical travel during typing is irreplaceable hence i prefer i hardware keyboard.

There was a prototype touchscreen developed by Nokia IIRC or a Japanese operator that could lift its surface for a few millimeters at a desired position, thus offering vertical travel and a touch screen that fooled your fingertips that vertical travel occurred via small electrical current but i don't know what happened to them.

When those become a reality, i might reconsider
