They don't need to. A lot of PC laptops feature high PPI displays. If you're using a moderately modern laptop, it's probably a high PPI display. A 14 inch laptop with a 1080p display is already at close to 160PPI. That's an option on a T480, a laptop from 2018. A P14S has an option for a 14 inch, 2880x1800 display, or 240+ PPI! The Dell Pro 14 has both an option for 1080p (~160PPI) and 2560x1600 (~215PPI). A 16 inch display with the same 2560x1600 resolution is close to 190PPI. Intel Macbooks Pro have had retina displays since 2012.
It's neither a novelty nor a Mac-only feature these days. A huge portion of the pc laptop market has high PPI displays and it's becoming increasingly rare to see anything that'd comfortably display at 1x scaling.
