I was looking for a specific laptop for my daughter that came in both 1920x1080 and 3200x1800 and the former was almost completely sold out everywhere. So I guess a lot of people prefer the lower-res. I felt the same way because if you have two laptops with identical specs but one has 4x as many pixels to push -- that's quite a trade off.
It's also the price difference - 4K have their use, and people appreciate them for different reasons, but yes I was in the same situation, and I felt ripped off for not buying the cheaper 1920x1200 or was it 1920x1080 option. This money could've go for a bit bigger SSD, or maybe more RAM. He really doesn't need more than that.
In my case, the price difference was actually negligible. I just felt the lower-res display was the better choice given all the variables: weight, battery life, performance, RAM, thickness, etc.
