@Jeff Brody: @joschh:
Much cheaper laptops sport FHD IPS displays with around 350 nits of brightness, 1300:1 contrast ratio, 95% sRGB and 70% AdobeRGB color coverage. MBPs and Surfaces have over 500 nits, 1800:1, and impeccable color gamut.
And here's a batch of "professional" and "business" laptops from Dell, HP and Lenovo that are more than x2 as expensive as the cheapest quality laptop, that only averages at 250 nits, 800:1, and 65%/40% on a same display config, with 250Hz PWM flickering to add to the insult.
(I don't know much, but my guess is that the Latitude 5580 and Precision 3520 use different displays, as they have in the past)
I'm not saying all business laptops have crappy displays, but most Full-HD non-touch IPS displays are garbage, and for some people, anything else isn't a viable option at the present.
