The fourth-generation ThinkPad Yoga X1 has swapped the finish of yesteryear for something a little more metallic.

Lenovo's new flagship 2-in-1 came as a bit of a shock after the sleek Carbon X1. Starting at 1.35kg, it's a heftier beast (something I certainly noticed in a shoulder bag) and the metal finish seemed a tad less luxurious than its sibling.
