If somehow you could have the same phone but with a resistive, single-touch screen and use it just like you use it now, then you would learn what:

a resistive screens do actually need to be pressed instead of just touched, if you never get a literal sore thumb from a touch screen usage - well you don't miss anything but it's quite painful after a while and adds to a carpal tunnel syndrome

a multi-touch sensor greatly helps when you need to discern and filter out the false positives
