The T430s is nearly identical to the T420s, maintaining the spartan, business look familiar in ThinkPad machines. At 13.50″ x 9.05″ x 0.83″ – 1.02″ (front to back), it feels thin, somewhat wide, and surprisingly light. According to Lenovo, the roll cage surrounding the key components is made of magnesium, and the chassis and lid are composed of “carbon fiber reinforced materials” to keep the weight in check, bringing the laptop to around 4 lbs. Like most ThinkPads, durability and fit and finish are impressive.
