The ThinkPad T450s features dedicated left, right and center buttons for the TrackPoint. This is a huge improvement over the 2013-2014 ThinkPads, which built all three buttons into the top of the clickpad, forcing stick users to move their fingers down further and push with much greater force. Lenovo got some well-deserved criticism for taking dedicated buttons away on the T440s, so the company deserves some credit for listening to its customers and bringing those buttons back on the current model.
If you prefer a more traditional touchpad, the ThinkPad T450s' 3.9 x 2.25-inch clickpad more than fits the bill. It offered smooth navigation around the desktop in my tests while accurately registering multi-touch gestures such as pinch-to-zoom, two-finger rotate and four-finger swipe for showing the task manager. Many gestures, including Windows 8's swipe to change apps, were disabled by default, but after visiting the Advanced Settings in Control Panel, I was able to turn them all on. I also found that it was easier to move my pointer across the screen in one motion after turning the speed of the touchpad up a couple of notches.
