The Lenovo Thinkpad T440s was released with the nigh unusable touchpad with integrated buttons, that was a complete disaster from a usability standpoint. Unsurprisingly the touchpad was replaced with a proper one in T450s which turns out to be compatible with the T440s. Should also work with T440p.

The laptop is now much more usable than it was before.
