Lenovo announced several PCs at Mobile World Congress this week, but the most intriguing is the ThinkPad X13. In addition to being Lenovo's first-ever ARM-based PC, the ThinkPad X13 is the first PC powered by the new Qualcomm Snapdragon 8cx Gen 3.

The ThinkPad X13 is a 5G clamshell laptop that only weighs 2.35 lbs (1.06 kg). Lenovo claims that the device will get up to 28 hours of battery life. Even if those battery estimates are lofty, the new business laptop should still last longer than most of the best Windows laptops.

While the ThinkPad X13 is not the first Lenovo laptop with an ARM processor, it is the first ThinkPad device with an ARM chip. That means the laptop combines the portability and connectivity of the ARM platform with the business focus of the ThinkPad line, and that includes security features. Microsoft and Lenovo worked together for four years to ensure that Lenovo's security software would work well on a Windows on ARM PC.

Our executive editor Daniel Rubino got to go hands-on with the Lenovo ThinkPad X13.
