I am becoming increasingly bemused by this thread. I start from the point that a typewriter is intended for, err, writing. (There's actually bit of a clue in the name if you look carefully.)
Writing is quite distinct from basic command input at the human-device interface. Every day many people will use a wide range of methods to interact with a phone keypad, cooker hob, microwave, electric shower, home entertainment system, games console, sat nav, fitness monitor, point of sale terminal, coffee machine, ATM, musical instrument, etc., etc.. These will use a variety of 'keys', buttons, knobs, swipes, menus, voice commands and so on. These generally get nowhere near the number of 'keystrokes' to write a report, assignment, story or whatever. Obviously it is sensible to use a device that is optimised for this purpose in terms of interface layout, ergonomics, screen 'feedback' and so forth. The QWERTY keyboard fits in here.
Although plenty of people do spend their days hacking away on keyboards I suspect that the majority don't by virtue of their occupation, lifestyle or age.
Strangely enough, not everybody finds typing 'easy' or a matter of practice or tuition. Even after decades of familiarity with manual and electric typewriters, TOPS terminals, computer keyboards, laptops, tablets, smartphones, etc. and having undertaken proper manual and electric typing courses at technical college I still have to look at every character as I type it, with a maximum of two fingers. And despite a lot of hands-on front line railway work that obviously didn't mean constant keyboard work, much of my life has been behind a desk.
When it comes to TVMs a few 'touches' seem neither here nor there in the overall scheme of things. At rural unstaffed stations the biggest challenges appear to come from rain-lashed screens, steamed-up glasses, sun glaring on the machine, trying to use one with wet sheepskin mittens, etc.. As a 'friend' of my local station these seem to be far more important issues as I try and assist despairing visitors.
