There really are many other apps that are useful besides just Google Maps though. It's great to have a phone that can play music for the gym, have an app like venmo for small transactions when you forget cash, or a portable e-reader for the bus or train, or uber for just-in-case situations... and many more. All of these aren't indispensable, but they just make life so much easier and better.

I definitely agree with you that removing social network apps is a great way to improve productivity a bit. And of course, if you don't need the apps listed above, then, yes, there isn't much point in paying extra for a smartphone. But please realize that many people are willing to pay for the significant convenience that a smartphone affords them.

Not using a smartphone just because of the battery life or durability though is silly. A specialized case will nearly solve both problems. There are privacy concerns and productivity concerns and price concerns, sure. But this is the future - and we should be trying to address those concerns and change them for the better, not fight smartphones altogether.
