I am surprised they didn't change the included lighting <-> USB cable to USB C. Out of the box still incompatible with the MacBook Pro, and forced to use dongles/adapters.
I am surprised that they still only include a 5W charger. Especially when they advertise fast charging with the 29W charger. Would have been good time to include 15W USB-C charger and USB-C to Lightning cable.
Why do you ever need to plug your iPhone into your mac?
To program iPhone apps. AFAIK, Until the recent Xcode beta you couldn't push code wirelessly to your iPhone, and even now the feature in the Xcode beta is pretty slow. Also I enjoy charging my iPhone with my macs. For a company that takes pride in seamless connectivity within their ecosystem I find it surprising that you cannot buy an iPhone + MacBook Pro and connect them without adapters.
You absolutely can; just not with the cables they ship with. There are lightning to usb-c cables available from both Apple and others now.
