Where is the smartphone heading towards?

When the iPhone was introduced in 2007, Steve Jobs clearly outlines the issues with the then smartphones, like the so called internet, wasted space for physical keyboards, etc. But as I was reading this article from MacWorld, I was wondering what would have Steve Jobs done if he saw the iPhone 6 or 6 Plus today and what would he change in it (assuming he never created the iPhone) to make a better smartphone? I have no clue, not even a hint.. 

The iPhone has homogenized the lineup to the point where the denominators are so common, you practically have to study the tech specs to find a difference: a few more megahertz here, an extra megapixel there. The smartphone war has become a battle of inches and millimeters, and while there are plenty of choices, when you pit the Galaxy S6 against the HTC One M9, or the iPhone 6 Plus against the Galaxy Note 4, the differences between them are getting a lot less obvious.

I totally agree with the premise of this story and this feeling is not something new or recent. I think this trend started as early as a few years ago, when no major innovations were taking place in the smartphones. Yes there are features like Touch ID and Apple Pay, but they are more extensions than redesigns. But what would you change in the iPhone 6 other than making it much faster, have more RAM, better battery life, etc? I for one cannot think of anything from the top of my mind. Computers faced a similar fate, the modern laptops haven't changed in almost a decade. Look at the Apple PowerBook G4 that was released in 2001 and now look at the 2015 MacBook Pro, that are 14 years apart. Yes the current model is thinner, more shinier, more faster, made of aluminum, but it has a clear close resemblance to the 2001 one and one can strongly argue that the basic form factor of a laptop has not changed. These two laptops don't differ as much as the first generation iPhone differed from say a Blackberry smartphone in 2007. Hence in summary I think we are going to be stuck with these "iPhone like smartphones" for a while and that might not be such a bad idea!
