The Dell Latitude 7400 2-in-1's 14-inch screen is one of its most revolutionary features. It's a full HD (1,920-by-1,080-pixel) touch panel that uses very little power, resulting in astonishing battery life when performing simple tasks that demand little of the CPU but a lot of the display, like video playback.

A 360-degree hinge lets you rotate the laptop however you wish, and despite the added mechanical complexity, the entire laptop weighs just under 3 pounds.

The glass-topped touchpad uses Microsoft's Precision Touchpad interface for simple sensitivity adjustments, but I found that it came perfectly calibrated out of the box. The island-style backlit keyboard, meanwhile, is extremely solid, with virtually no flex in the middle.

The Latitude 7400 2-in-1 has a sleek soft-touch metal chassis. The entire laptop, clad in dark gray aluminum and sporting diamond-cut edges, looks far sleeker than notions of an IT-issued machine might prepare you for.

Sound emanating from the Latitude 7400's two downward-firing speakers is adequate, thanks to digital audio processing from the Maxx Audio Pro driver that adds dimension to the sound output. But even digital sound processing can't overcome the tinniness and lack of bass.

You can use the Latitude 7400 2-in-1 with an optional active digital stylus. I mostly tapped with my fingers, however, and I found the display hinge to be exceptionally sturdy, with very little screen bounce.

On this edge, you'll spot a Noble-style security lock slot, a second USB 3.1 Gen 1 Type-A port, a micro SD card reader, an audio-out jack, and a nano SIM card tray for the optional LTE modem, which isn't present on our review unit.

This side features two USB Type-C ports with Thunderbolt 3 support, either of which can be used to charge the laptop using the standard 65-watt or optional 90-watt power adapters. Also here: a USB 3.1 Gen 1 Type-A port, and a full-size HDMI output, a must-have for frequent connections to conference-room or lecture-hall A/V systems.
