One of the features they highlighted is is the built in display has very similar specs to their 6K 32" professional display (which, by the way, costs more than this laptop). So when you're not working at your desk you'll still have a great display (and why are you buying a laptop unless you occasionally work away from your desk?)

• Both have a peak brightness is 1600 nits (a Dell XPS will only do ~600 nits and that's brighter than most laptops).
• Both have 100% P3 color gamut (Dell XPS only gets to 90% - so it just can't display some standard colors)
• even though it's an LCD, black levels are better than a lot of OLED laptops
• contrast is also excellent
• 120hz refresh rate, which is better than their desktop display (that only runs at 60Hz. Same as the Dell XPS)
• 245 dpi (again, slightly better than 218 dpi on the desktop display, although you sit further away from a desktop... Dell XPS is 169 dpi)

I love Dell displays, I've got two on my desk. But even the Dell displays that cost thousands of dollars are not as good as Apple displays.
