finally paid up for a digital av adapter ,and hdmi>dvi en route for driving a 24" display (HP ZR24w). Not the best, not the worst though either and 16:10 gloriousness. it should be cheaper if not included but thats apple for you and greed winning. and 12" next to my 24' looks great, delicious even in terms of expanding this thing out. anyways i had a 2011 air and a thunderbolt dock for a while. between downsizing the 13.3" to this 12", getting retina (though dabbling with rMBP 13" in between), and now this digital av dock reminds me of my thunderbolt dock but shrunken down to the basics: display, power, and usb3 which is all i do. i have a usb 3 hub too. I'm continuously sort of admiring power+data over one cable now that I'm putting it to use. got a usb-c to a black monoprice cable on the way too for on the go situations. i also sold my thunderbolt dock for above what i got mine for used, so the dongle is less of a blow to the wallet. consider me a skeptic turned a fan!
