I have both an external display and use the Macbook Pro’s keyboard. My controversial view: I like the feel of the MBP keyboard, appreciate the convenience of Touch ID, and like the functionality of the Touch Bar. To view both displays, it helps to have the external monitor elevated over the Macbook Pro. This keyboard tray is reasonably sturdy and permits a comfortable typing height.

I travel often. It’s nice to have a light 3 lb laptop for travel that also connects to a 27" retina display for a home desktop experience.
