You'll like the way Apple does their screens even more then. They're 3-5k screens but they essentially scale up their UI 3X so it still looks like a 1080p except 3x sharper.
If you can't see the extra sharpness it's not really a pro...
A 13"-15" 1080p screen is pretty similar PPI to a 27" 4K display. This is pretty nice because if you have both at the scaling level elements are the same size on both.
