Yeap. Same dilema here, splitting in two or three when coding doesn't look good in my LG 27" 4k monitor. Is either full screen or nothing. For the case, instead of buying 2 32" apple pro monitors buying 3 of the 27 would make it better.
I think I'll buy one and maybe buy two more later if it proves to be good, almost $5k though, ouch... Wish they made a simpler version with no ports, no camera, no speakers, etc - why would I need 3 cameras and 3 sets of speakers?..
