Thinner and lighter. Thinner and lighter. If the smartphone world had a drumbeat, it would sound like the phrase “thinner and lighter”, with the occasional “more battery life” thrown in. Apple has certainly taken to the “thinner and lighter mantra”, without dropping Apple’s traditional love of upselling users on expensive extras using proprietary ports. Remember firewire? Apple will more than likely get rid of the 3.5mm headphone jack on the next version of the iPhone.
It’s all about lighter and thinner for Apple, despite the fact that the iPhone already has issues with being too long and too thin to be kept safely in the back pocket without shattering the screen (this actually happened to my wife) or bending the unit. Apple, in its infinite greed/wisdom, has decided that changing from the 3.5mm standard headphone port to a Lightning port used for headphones. (Does that mean that Apple will both charge the phone and power the headphones with the Lightning port?)
Even if Apple makes the change, someone’s going to sell an adapter for the phone to allow continued use of real headphones. However, Apple’s future is going to be that Lightning port, even if they bow to public pressure–again–and save the 3.5mm headphone jack.
