I've been eyeing this monitor since it was announced. Seeing the first couple of YouTube impressions and reviews made me want it even more. But something is going on. Either LG completely understated the demand for it and can't fulfill orders quick enough, or they are having supplier issues, or something is going on regarding manufacturing problems.
It's a shame. Having more horizontal space like that would be a godsend in professional applications for music and video, but I was always hesitant in buying into the smaller 1080p versions of the ultra widescreen format. 4K @60Hz is not quite ready for mass adoption just yet, so this would be a perfect middle-of-the-road approach for a lot of people, especially at the $899 price point.
Will just have to wait and see. Hopefully ASUS, Samsung, and Dell are noting the demand for these and will come out with comparable units that you can actually buy.
