Perhaps no business ultraportable is better known than the Lenovo ThinkPad X series, headlined by the long-running ThinkPad X1 Carbon. The ThinkPad X390 is the latest in the famous lineup, now packed with Intel's "Whiskey Lake" silicon and delivering more than 14 hours of battery life in our testing. Its trimmed-down design allows it to fit a 13.3-inch screen in a footprint similar to that of the 12.5-inch ThinkPad X280 that it replaces. Priced aggressively and marred by few downsides, the X390 is an easy Editors' Choice pick among high-end business ultraportables.
