Why I Still Use an iPhone 4

While the 5S is a pretty awesome phone, I have to agree with the author that it doesn't enable us to do anything fundamentally different than the 4. The major generational innovations:

3G - 3G data 4 - Retina display, FF camera 5 - LTE, screen size

All of those things are nice, but they simply make use of the phone faster, at a higher resolution with slightly more screen area. So I can check Facebook faster on a nicer screen.

I'd like to see some fundamental improvement in user interaction, something that enables us to do things we couldn't before. Google glass is pointing in that direction, but it's still along the same vein of more immediate, always on computing power. I don't think we've fully tapped the innovations that these devices can allow.

For example, I think the idea of the universal Ubuntu phone would fundamentally change the way people saw their phones, because it would allow their phone to become their ONLY personal computer by simply plugging into additional human interface devices (larger screens, keyboards).

tl;dr "It does everything that I want it to do."

I'm almost 50. I've been hearing this one since the Commodore 64 days.

I think the Lumia 1020 has introduced some pretty awesome features. In fact I think Nokia is the only company (soon to be Microsoft) that is innovating in the mobile space. *I have an iPhone 5 and probably won't switch ... MS needs non-ported apps.
