Even if you never use it as a full tablet, having the two-in-one design makes sense for professionals, letting you switch easily from creating presentations to giving them. Or if you just want to relax and watch a movie on a long flight, you can get the keyboard out of the way and focus on the nice, bright full-HD display.
When you're not traveling and want to dock it at your desk, the 7390 has you covered with ports both old and new. While it has two USB-C ports with Thunderbolt 3 optional, you'll also find two USB 3.0 ports, an HDMI 1.4 output, a combo headset jack and a microSD card slot. The USB-C port is used for charging and works with the company's Hybrid Adapter + Power Bank, which can be used for powering the laptop off an outlet or its 12,800 mAh battery.
Overall, I really like the design with maybe the exception of the keyboard which just felt small. Fast typists might need to slow down some for the sake of accuracy, at least until you adjust to the size. The touchpad is just fine, though, and has discrete mouse buttons instead of a big single clickpad.
You get back what you put in
Performance on my 7390 was excellent, but it was also loaded with the higher-end components Dell offers: 1.9GHz Intel Core i7-8650U vPro processor, 16GB of 2,133MHz RAM and a 512GB PCIe NVMe SSD. The base model, on the other hand, is decidedly low-end with an older seventh-gen Core i3 CPU, slower 4GB of 1,866MHz memory and 128GB SATA SSD. For day-to-day office chores like email and word processing, that entry-level config will be enough. However, you might find yourself slogging through any intensive tasks -- anything from working in large databases or spreadsheets to creating multimedia presentations -- and cursing not going with more memory, a faster processor or SSD.
The same goes for your battery, too. The base model has a 45Whr three-cell battery while the one I reviewed has a 60Whr four-cell battery. The larger pack ran for 10 hours and 22 minutes on CNET's video streaming battery rundown test. It should be enough to get you through a day of work, but if you start to run low, the battery does support fast charging that will take its battery to more than 80 percent in an hour.
Business you won't mind
As office systems go, the Dell Latitude 7390 2-in-1 is no clunker, giving you the flexibility and potential performance of a higher-end consumer PC with the durability and security options you'd expect in a modern business laptop. If your primary concern is keeping your data private at all costs while you're in the office or on the road, this should have you covered. But if your IT department offers you one, make sure you get something better than the base model.
