From my time as a volunteer high school tech support helper, I remember the first year that Dell shipped us laptops without the external floppy drives. This was annoying to many of the old-timers who had established techniques around booting from a floppy.

We got over it.

We don't understand touchscreens well enough yet. We are using an old metaphor (the keyboard) and porting it completely literally. We might never replace the keyboard fully, but surely there is room to innovate.
