I understand why he needs better, but really applying his needs on every Mac user is way WAY overboard. If he said it's not good enough for him, you wouldn't have heard a peep from me, but since I am a Mac user and he said 4K wasn't good enough, well, that's just incorrect for me.
As for 32", I'd probably throw anything that big or bigger away if I wanted to use it with a computer, but that's just because that big would be harsh close to my face! I also wont pay $1600 or more for a monitor, any monitor, I'd never get my money's worth out of it. The minor stuff I do photo-wise doesn't pay any of my bills, nor do I want it too, as I make enough being an IT Manager.
