Even after months with the glorious panel in the LG and using the 15" retina as second display, going back to big ole' country pixels was almost a price I was willing to pay for ultrawide. I think the 2 x 28"s is the right choice for me, but only by a gnat's dick.

If I could have beaten my Mac into driving the LG at a non-2x scale, I'd have kept with it, it's such a nice panel. But now it's on my Win 10 box, which supports it perfectly; that was a very pleasant surprise.
