Apple is planning to replace the standard 30-pin dock connector that is used in the iPhone, iPad and iPod with something more compact, according to iMore.
An updated “micro dock” would make room for bigger batteries, 4G radios, and other components far more important to the iPhone and iPad in a PC free world.
We’ve heard that Apple is getting ready to ditch the dock connector as it’s currently sized and implemented on iPods, iPhones, and iPads.
As iMore points out, the reason for replacing the 30-pin connector with something more compact is to make room for components for next generation iOS devices, such as 4G radios, bigger batteries, new sensors etc.
However, replacing the standard 30-pin connector would result in compatibility issues with existing accessories that make use of the dock connector (unless it also provides a convertor). Apple has been quite prepared to take such hard decisions to achieve the goal of making their iOS devices thinner and smaller in the past. For example: Apple was one of the first companies to start using micro-SIM card.
iMore also makes a valid point that with introduction of PC Free features such as Wi-Fi Sync, AirPlay and iCloud, the importance of the dock connector has changed.
It is probably wishful thinking, but it would be nice if the mobile industry sat down and came up with a common standard that could be used across mobile devices to reduce the cable clutter.
