The ThinkPad X1 Extreme is back with some fine improvements that make Lenovo's 15-inch Ultrabook better than ever.

Dell's formidable XPS 15 9500, one of our favorite 15-inch powerhouses for years running, received some competition in 2018 when Lenovo released the first-gen ThinkPad X1 Extreme. It received rather high praise, especially in terms of the overall design and included features, and now the second generation is here. It's been updated in a number of small ways, equalling up on paper to an X1 Extreme that's never looked so good. We've been using it for a couple of weeks to see how well the changes work in the real world and, ultimately, whether or not the second-gen X1 Extreme is right for you.
