Seriously? Couldn't they have put _two_ ports in it so you can plug something in while it's being charged without lugging around a usb hub?
With that battery life, I don't suspect I'll ever be charging it while using it - I'll only ever charge it while I'm asleep.
Given it's USB-C there'll be plenty of hubs, docks etc... but it'd have been nice to get it out of the box (charger being a hub), or at least having two ports.
1 port is just ridiculous, it's basically 'we force you to make big tradeoffs, like an external screen or charging, unless you want to buy and carry with you various externals for what is supposed to be the most portable device in our Mac lineup'.
Lack of an SD card is another one of those things. Not as big of a problem but would 2 ports have really been that difficult?
