I have clocked how much time it takes for when you hold finger down on touch screen on the ipad so you can copy/paste something..
It takes approximately 1sec
The following is calculations for how much time a day/year spent..
Doing this 10 times / day.
10 times / day = 10 seconds a day
3650 sec/year or 61 minutes
The following is for 5 times/day..
5 times / day = 5 seconds/day
1825 sec/ year or 30 min
