Panasonic has launched two new handheld Toughbooks for the workplace, and in addition to being rugged, they also have removable batteries. To be precise, the company says their batteries are "warm swappable," which likely means they can be replaced without rebooting the devices. The Toughbook T1 phone has a 5-inch display and runs Android 8.1 Oreo -- it's obviously a lot chunkier than other phones on the market, but that's to be expected for something that's part of Panasonic's range of rugged devices. The Toughbook L1, on the other hand, is a 7-inch tablet, which also runs Android 8.1 and is protected by thick corners and bezel to make it drop-resistant.
