It's more precise when operated without moving hands away from the keyboard. I can almost play dota or FPS games to the same degree I can with a mouse with the clitmouse, such things can't really be said about the trackpad. There are also 3 distinct buttons which I find handy - I don't recall exactly how trackpads solved the right mouse click or middle click issues - so whilst I miss out on the gestures, I find I can do about the same things with keyboard shortcuts or extra buttons on the mouse (scrolling with the middle click and moving the cursor).

However, extended use does induce tension in my wrist - hence I prefer not to play games on a laptop. The first thing I do when I get a new laptop with a trackpoint and a trackpad is disable the trackpad. If the glorious fruit company offered laptops with trackpoints, I'd do the same. I don't believe that a trackpoint is better than a trackpad in every conceivable way, but it does fit my way of using my devices far better than trackpads do. However, I also don't believe that there will ever be a trackpoint on a glorious fruit device - they don't allow for multiple ways of doing the same thing, and I'm very aware that most people do prefer trackpads to trackpoints. I just hope that my niche will be served by someone until I no longer want to use laptops.
