How many other people here cannot use a touchscreen device (iPhone, iPad, Android)?
90% of the time when I touch, tap, gesture etc..... it never registers.... UNLESS I use a stylus of some sort.
My wife can use the exact same device, doing the exact same things and it responds as it should.
I have read somewhere that 10% of the population have this issue....... yet Apple and the others continually go more and more towards a button free device.
Oh and that 10% does not include people with accessibility issues for other reasons...
