$1600 for 128GB storage and non-upgradable 8GB memory is a bit much. The rumored selling point of this laptop was its 78 Wh battery, yet there's no mention at all in Dell's products page.

Should you want a real matte touchscreen, HP EliteBook series offer a variety of etched-glass panels with some of the highest brightness in the market, from 450-nit FHD up to a 1000-nit FHD.
Otherwise, there are dozens of high-end laptops with 500-nit glossy screens from FHD to 4K UHD, both touch and non-touch, which can be applied with 3rd party matte screen protectors. This route is possibly the most ideal if you want a outdoor visible matte display on your laptop.
This particular Latitude laptop has a standard FHD glossy display (300-nit, 60% AdobeRGB, 1000:1) that can be found on most $600+ laptops with identical specs.
Between the two laptops, S940 UHD is the better choice, as long as you're fine with 5 hour battery life and relatively high price tag.
