So you saying you buy it for $600? Or are you saying you'd take one for free and review (and probably return post review)?
Outdoors makes a lot of sense as because it total you have less volume than a TV and you can always hang a sheet off the inside largest surface. But then it isn't really designed for the outdoors also as its an AC charger and the manual warns of dust and moisture.
Pair with some decent charging options like Powerhouse. It is odd they have a non-USB charging input, so it can't be charged so easily off cigarette lighter USB outputs. So it seems somewhere halfway between it suiting situations where isn't a big screen, it is portable, and yet not designed for outdoors. The vents are one reason, it will suck in dust and any splashes.
