The best benefit is indeed not taking hands off main keys on the keyboard to move around. Old Toshiba Tecra's trackpoints were notorious for their drifting into some direction after they've been used for a while, some sort of sensor preference. The ones on P and T lines of Thinkpads are totally the only way to go. I swear by mine on my old P50 workhorse, but alas, my new work laptop doesn't have one. Another challenge is not misplacing the extra nubbins that came with this back 6 years ago...
