@JimmyPage "automotive market is completely mature"
How is the smartphone market not mature? What major breakthroughs have occurred in the past five years? I can't name one. CPUs got faster, more cores, better GPUs, 64 bits, etc. You got more RAM, more flash, newer wifi and wireless standards. Screens got bigger and higher resolution. Cameras got more megapixels and better light sensitivity. None of this compares to when a GPS got small enough to include in a phone and made using it for mapping possible, nor when capacative touchscreens rid us of the keypad.
All of this is just following technological progress. Cars get improved electronics every year too, its just that nasty mechanical stuff like engines aren't subject to Moore's Law so the improvements aren't as obvious when measured against the total driving experience. But most wouldn't be willing to give up their ABS and stability control that Moore's Law made possible. Modern cars make a lot of use of LEDs for exterior lights (and even in some cases headlights) which eliminates the problem of a single burned out bulb leaving you without brake lights or a turn signal.
The smartphone market is mature, all of those who talk about how Apple needs to "innovate" in smartphones are missing the fact that no one else is innovating in smartphones either, unless you consider gimmicks like a curved phone to be innovation. Something like that is akin to Ford putting out the Mustang with a new body style, its not exactly the invention of AWD or even four wheel steering.
Technological progress continues, but there isn't really anything on the horizon that we're waiting to integrate into a smartphone that isn't quite there yet. Not that there isn't progress for things that could be integrated, just that none are going to be a game changer. They're now able to make atomic clocks small enough to put inside a phone, but who needs that? Maybe someone will come up with a need for time accurate to the picosecond that our current ability to have time accurate to a few milliseconds wouldn't be good enough for - if so, coming up with that use will be the innovation, not the first phone to have an atomic clock in it.
