I'm not a high end user. I use it for photoshop and Lightroom. I love the screen and it's big enough for me to watch stuff on it and be happy. If I was to build this in a PC, It would be too expensive I would bet. How much is a 4k screen at 27"?
Maybe I don't need a k4 screen, but I like this all around. Ive been using a 21 inch iMac at work for 7 years and it's the only computer left not replaced. All other PCs crapped out.
I'm not a computer person that tinkers. Give me something nice and I'm good for a while.
A 4K display runs around $400. 5K is pretty much exclusive to Apple though.
