I ordered a second 5K that arrived today so I had one for home and the office. I didn't need it, but honestly, it could be a while before a monitor like this is available at the price point and after using one at the office all day, it's amazing how pixelated my old 27" LED Cinema Display looks (not to mention washed out).
I've been using my first (without the shielding fix) since late January. It's not perfect, but the panel itself is—by far—the nicest panel I have ever used. 5K is nice in and of itself, but the color cannot be understated. I actually prefer it to Apple monitors in the sense that I like the black and hey... LG isn't morally opposed to standard VESA mounts or an adjustable stand. (No cable management is a bit of a head scratcher but it's nothing velcro can't fix.)
Also, single cable is just cool. I know it's a little thing, but it's a nice little thing. If you haven't seen/used one in person, you should do it ASAP if you're on the fence. I read a lot of negative reviews and, quite frankly, if you're giving this display 1 star because you don't like the look... you're not someone I should take advice from.
