The trouble is Apple aren't changing adapters for innovation, they're changing it so they can over charge for items that do exactly the same as existing hardware and tech. When was the last time they actually innovated? I'd say the original iPhone was the last piece of innovation and since then everything has been an 'evolution' of that.
Pragmatism is hardly being afraid of advancement, if they go wireless for example, how do you use their product to listen to music and podcasts on a plane when if caught most airline staff request you remove headphones that are using bluetooth or wireless technology?
the phone will still have a lightning adaptor more than likely. they are innovating the last standard analogue port, which is for all its worth a very old piece of tech.
pragmatism, i call it problem finding.
so instead of just sticking with old methods. how about solve the problem.
I'm pretty sure there has been no link to using mobile phones and bringing down airplanes. so, why are we not allowed to use them on an aircraft.
sorting this will be the answer. not "don't bother" as airplanes will not let you listen.
even then, they are changing the port, not insisting on bluetooth.
what you will find is the girls with the power bricks in their bags will be the power users who can't help but spend every waking min hitting up the cellular network.
but, this is a problem. but with every new phone batteries get more advanced with higher energy density.
they make the phones more powerful and at the same time, thinner and lighter. they are working towards targets.
they will adjust targets for battery life at some point if it was deemed that enough people are draining their battery.
also, it's not just apple that are developing in this way, they are all at it. If it was as much of a problem as you make out, start your own phone company, buy an open source phone platform and strap a stinking battery to the back. include a million old school ports. hell, an ariel that can be extended out like the 20 year old phones, so then you can have better signal......
