Initially there was a lot of futzing, because the hardware just came out (UHD 630 Intel graphics). Some things like Nvidia graphics and SD card reader won’t work because of missing drivers, and are unlikely to work in the future.
That said, I use this setup every day and mostly forget it’s not a Mac. I was quite frustrated by the new Touch Bar Macs issued by my work (unpleasant keyboard, no real F keys, USB C only, flimsy back case that has dents in it from regular commuting use somehow), so I didn’t see that as a viable upgrade path for me since I like to keep my computers for 5+ years.
That’s probably not very convincing, but for me it was the right choice. For what’s its worth, I intend to support the XPS 9570 as a Hackintosh platform until at least 2023.
