Unfortunately, the screen's mediocre color quality and viewing angles leave much to be desired.
Unfortunately, despite the good layout, an uncomfortable palm rest prevents the T431s from providing the industry-leading typing experience we've come to expect from a ThinkPad. The ABS plastic-on-magnesium deck was so hard it felt like our wrists were resting on a stone and its right side got distractingly warm
As usual, the TrackPoint provided extremely accurate navigation around the desktop. Its built-in buttons responded accurately to our touches, but required more force to press than the old dedicated ones; our finger had to push down the entire touchpad rather than just one small button.
The T431s offers a few new riffs on the tried-and-true ThinkPad design aesthetic, but most of these changes make the laptop seem more functional and less attractive than its predecessors. Instead of the deep raven black we're used to seeing on ThinkPads, the T431s uses a blander "graphite black" that seems almost gray in direct light.
