You always could do that, just that you needed to purchase an additional cable. But otherwise, it was very much doable.
I think you missed my point..
I bought two top of the line products, MacBook Pro and iPhone X and couldn't connect them out of the box.. Ofcourse I can buy another cable, I know its doable, anything is doable..
Their logic is hard to understand, 2 different strategies. They commit to Thunderbolt 3 (USB-C) but don't get rid of the headphone jack on the Mac.. They get rid of headphone jack on iPhone but give you the cable so that you can still use a headphone jack until you transition to wireless options.. I just bought a Magic Mouse 2 and Magic Keyboard and they come with the USB cable, I am hemorrhaging USB cables, there is nowhere to plug them on a modern system..
Maybe they could lower the prices of the products slightly and the cables could be sold separately ?
