I'm very happy to adapt to new things, when they offer a demonstrable benefit to me. What benefit does a USB-C keyboard give me, exactly? I don't need the extra bandwidth to transmit keypresses. Why not include one or two traditional USB3 ports alongside the USB-C ports to ease people over to a new standard?

I don't really need a laptop to be so thin, but it's a defining feature for Apple's "premium" feel.
It takes time before you can see the demonstrable benefit. For starter
- USB-C solves the which side to plug in issue
- It's a unified charging port besides data transfer (one charging cable for all devices in the future)
- It's also a unified display port (one display cable for all devices in the future)
For coming up with that sentence, everyone here owes you a beer.
That you can connect it to phones with USB-C without any dongles. Almost all new phones have USB-C. Except one from Apple.
