A bit tangential, I have been pretty content with Apple's relative stability on their proprietary connectors on their mobile devices. Just look at the mess of variants for USB: https://en.wikipedia.org/wiki/USB_hardware https://en.wikipedia.org/wiki/USB_hardware While I've only had to deal with 2.5-3* transitions for my Apple devices so far. * Apple of course did cause their own mess transitioning away from Firewire while keeping the 30-pin connector: - 30-pin Firewire data + charge - 30-pin Firewire charging only - 30-pin USB, no firewire charging (Remember all those Bose dock/car 30-pin adapters). - Lightning port transition. In this case, Apple's proprietary ports ended up feeling a lot more universal.
