No! Modern smartphone combines many things in one and simplifies your life in that sense. I play music, use turn by turn GPS, read books, newspapers, and magazines (though mostly on tablet, to be honest), listen to music and Internet radio, watch videos and photos, use instant messaging, check calendar and todo list, write diary, keep my boarding passes, buy movie tickets, check weather forecast, set alarms and kitchen timers - all one small device sitting in my pocket. And oh, sometimes I use it as a phone too.

Smartphone made my life much, much easier.
