and don't forget missing USB-C connector! I can charge all my 15 devices in a travel via a single cable, but Apple users have to carry another charger (or adapter) just for smartphone...
Not that I don't love usb-c ubiquity (thanks EU). It rwally grinds my.gears that my new kindle was syill micro-usb. Anyway, for those cases I have a couple of cheap adapters that do lightning/usb-c/micro/mini that I got free as marketing promos. Pretty handy to keep in your bag, especially for taking pity on people with dead iphones.
