What do you miss in the smartphones when compared to the old NOKIA phones?

We all had our experience with old NOKIA phones which wouldn't crack even if it's thrown from the edge of the world!
Those were the days and the memories are too precious to ignore.
Now that we have delicate multifunctional smartphones, who here miss any of those NOKIA phones?
I mean, smartphones are 1000 times functional in performance when compared to the oldies.
But we do miss the NOKIA in some corner in our hearts, right?
Why is that?
