Is there a better alternative?

The HP Spectre x360 13 has a slightly smaller display, but it rivals the Latitude 7400 in battery life. That is, it might also last you into a second working day, and it’s our longest-lasting 13-inch laptop. It’s also severely less expensive at $1,520 ($1,420 on sale) for a similar 8th-gen Whiskey Lake Core i7, 16GB of RAM, a 512GB SSD, and Intel’s low-power Full HD display.

　　If you want to stick with a 14-inch display, then the Lenovo Yoga C930 is an option. It’s equally robust, but it’s stuck on last year’s 8th-gen CPU and doesn’t have nearly as good battery life. It lists for $1,800 ($1,412 on sale) for a Core i7 CPU, 16GB of RAM, and a 512GB PCIe SSD. That’s roughly half the price when discounted, and you get much better audio quality in the bargain.

　　Of course, if you’re a businessperson, then you’re most likely going to take at least a look at a Lenovo ThinkPad. The most relevant alternative among this iconic line of business laptops is the ThinkPad X1 Yoga, a 2-in-1 with the same kind of 360-degree convertible design. The X1 Yoga is just as rugged as the Latitude 7400 and is subjected to the same MIL-STD-810g standard, but it doesn’t provide nearly the same kind of battery life. You’ll spend $2,400 ($2,160 on sale) for a similarly configured X1 Yoga, except the CPU will be the previous generation Core i7-8650U with vPro.

　　

How long will it last?

The Latitude 7400 2-in-1 feels like it will live through the apocalypse, and it has the most up-to-date components. Even better, Dell provides an excellent 3-year warranty that will keep you covered for much longer than the usual consumer laptop’s 1-year warranty.

　　

Should you buy it?

Yes, if you have the money. It’s the best Full HD 14-inch 360-degree convertible 2-in-1 you can buy, especially if battery life and security matter to you.
