Lisa Gade reviews the Lenovo ThinkPad X12 Detachable, a 12.3” Surface Pro competitor with a 3:2 aspect ratio display and a pleasingly rigid and ergonomic detachable ThinkPad style keyboard. It runs Windows 10 on Intel 11th gen CPUs with Iris Xe graphics and Thunderbolt 4. The X12 has a magnesium alloy casing and passes a variety of MIL SPEC tests, yet its weight is close to the Surface Pro 7. The tablet supports pen (included with US models) and touch, has optional 4G LTE, a backlit keyboard, Windows Hello IR camera and a fingerprint scanner. This is Lenovo’s first detachable ThinkPad since the 2018 ThinkPad X1 Tablet.
