The Trackpoint seems redundant to me because I can manipulate the trackpad with my thumb without leaving the home row, and for me it's faster and more comfortable than a Trackpoint.
Using your thumb to control the trackpad works better on Mac laptops because the Force Touch trackpad allows you to press anywhere to click. Most PC laptops have a "diving board" click mechanism which means it gets progressively harder to click the further you are from the bottom, and clicking near the top is impossible. Also, Mac laptops position the top of the trackpad closer to the keyboard than other laptops I've seen.
You can use tap-to-click as a work-around for being unable to click the top of the trackpad, but I find tap-to-click less usable for other reasons.
Is there a way to middle click with this method? I use that often for new tabs and ThinkPads have the physical button at the top and tap to click is just three fingers.
