The ThinkPad T440s is the slimmed down version of Lenovo's 14" T Series business laptop. With each iteration the "s" model gets even slimmer and lighter, and the new Intel Haswell model weighs just 3.6 pounds and is 0.8" thick. It has a backlit keyboard that's spill resistant an internal roll cage for strength and a carbon fiber and magnesium casing. We look at the model with a lovely full HD IPS display, Intel Core i5 Ultrabook CPU and an SSD drive. The laptop has plenty of ports and it features Lenovo's new Power Bridge system with hot-swappable batteries plus an internal permanently installed battery.
