Design
This notebook is mostly made out of plastic. So, keep in mind that its body is extremely scratchable, so you might want to keep sharp objects away from it. On the bright side, the lid is aluminum and kudos to Dell for shaving off a couple of millimeters and some 130 grams of the overall weight of the device.
Ports
On the left side, you will find the power plug, an HDMI connector, as well as two USB Type-A 3.1 (Gen. 1) ports and one USB Type-C 3.1 (Gen. 1) port with Power Delivery and DisplayPort capabilities. Switch sides, and you'll see an archaic USB Type-A 2.0 port, a headphone jack, and a MicroSD card slot.
