Until they can make wireless signals as reliable and as fast as a wired connection, that whole "fully portless" concept is absolutely ridiculous. Hell, I can't even currently do a wired file transfer from my computer to the Files app on my phone. Only way to natively move something across is through AirDrop or iCloud. AirDrop is incredibly unreliable when trying to move multi GB files, and I shouldn't have to wait for iCloud to sync.
