Until smartphones came or until early 2012, when you need to call to any local restaurant or any other place, you pickup your phone, dial the entire 10 digits and connect to someone on the other end.
With phone becoming smart, lot of simple task became much simpler and error free. With iPhones and Android phones, now if we want to contact some place, just search in Google, get the number and just Tap on it, it dials up that number for you and connect to that place. It takes out complete scenario of wrong number and keep looking for number here and there.
This is just one simple example of how the day to day activities are becoming more obvious and as straight-forward as possible. Another example, clicking on address and that opens up Map for you instead of tying confusing addresses into your GPS!
