One should be at the bottom one at the top. I understand space on the phone is a premium but a second port would make the phone so much more usable. Wired headphones, flash drives, camera modules, speaker modules, keyboards, even connection to a TV, all could be used while charging. It’s a shame it’s not a thing, USB is extremely versatile port, but you only get one and it’s used for charging half of the time. (I am aware dongles exist)
I’m sure Apple is working on some new wireless standard called “magic connect” or some shit like that. It will be 13.8% better but make all previous devices obsolete and incompatible pushing people to trash their old stuff and buy some new overpriced, proprietary stuff.
Then when they introduce this new standard, their next presentation slide will pat themselves in the back because they are such a “green” company.
