Thanks for putting this guide together Jamie 
You’ve definitely got me curious, especially with rumoured new iPads next week that are said to have a USB-C connector which may allow use of an external 4k display.
I’d actually love to see more portable, dockable computers whether they be iPads or MacBooks with single cable / docks. Bit like the new MBPs where they just needed a single cable to connect to the (5K) monitors which also charged the computer while also connecting to peripherals such as external drives, card readers etc… simply plug in and your set, unplug and go.
