At 0.7 by 12 by 8.2 inches (HWD), the Latitude 7390 is more compact than HP's EliteBook 830 G5 (0.7 by 12.2 by 9 inches) and even a tiny bit smaller than Lenovo's ThinkPad X280 (0.7 by 12.1 by 8.3 inches), despite the latter's 12.5-inch versus 13.3-inch display. (The Dell XPS 13 is smaller still, at 0.46 by 11.9 by 7.8 inches.) The Latitude weighs a trim 2.8 pounds, again undercutting the EliteBook 830 G5 (3.3 pounds) but not setting any records. (The wildly light LG Gram 13 weighs a waiflike 2.01 pounds.)
Port selection is impressive. On the Latitude's left side, you'll find a SmartCard slot, USB 3.0 and HDMI ports, a Thunderbolt 3 port, and the power connector. (The last is a proprietary plug, not the USB-C charging of the Latitude 7390 2-in-1.) On the right are an Ethernet port, another USB 3.0 port, micro SD and SIM card slots, an audio jack, and a Noble lock slot for securing the laptop to an antitheft cable.
