The appeal of a smartphone for me isn't any of the apps or games. But it is nice that it combines a sat nav, phone, camera, calendar/alarm, SMS/email into a single device.
So whilst you won't find me checking social media on mine, if I'm more than 5m away from my house you will see me using the maps

(I'm so directionally challenged and useless at finding my way anywhere, it's absurd!!) And I do use it as a memory aide to make sure I don't miss a dentists appt, etc.
I guess mine is really just a glorified PDA.
But how anyone can use them for web browsing or gaming I have no idea. Stare at a tiny screen for so long? Not a chance. But then my eyesight is crap. And more importantly, I hate social media/web 2.0.
