I have owned/used a number of ThinkPad laptops for approximately 20 years and have found them to be good, reliable machines. My only major complaint, historically, has been that the mouse/trackpoint will act erratically at times and begin to move across the screen. When this happens the only solution is to let go of the mouse, let it finish the erratic behavior, and resume activity. I have always been frustrated with this but am now extremely disappointed to find out this new T590 exhibits the same behavior. Specifically, this new machine is the WORST one to exhibit this, far worse than any previous machine. I am not the only to experience this phenomena and am disappointed that this issue has not been addressed and corrected in 20-some years.
