Yes. The arguments for it are the exact same ones Vim evangelists make (ergonomics, speed), but having the TrackPoint there applies those advantages to every other program on the system as opposed to just the one.
The trick is to use the stick as a Force sensor, instead of treating it like a capacitive Position stick on console controllers. In other words, you use your skin to "pull" the stick transversely so that the shearing force maximizes the feedback to your fingertip's cutaneous nerves.
The common mistake for those who gave up after 5 seconds of trying is attempting to "push" against the stick which is very difficult to do because there is barely any height to the nub, and in order to reverse directions you'd then need to shift your fingertip to get leverage on the opposite side of the dome.
When you instead use the shearing technique, it enables considerable finesse over not just the magnitude but also rapid modulation of the direction you are applying it in, effectively using the skin itself as both a sensor and a transducer.
Also remember to turn off the operating system's mouse acceleration, and turn up the driver's pressure sensitivity to max.
Are you touch typing? I am sincerely curious. For me, because I am touch typing, the trackpoint was a big advantage over the trackpad - I don't have to lift the hands from the keyboard. This is how I got used to the trackpoint.
Yeah, I tried repeatedly with an IBM laptop years ago to get used to the nub, and couldn't get accurate with it without dropping to like 1/20th my mouse-using speed. Even the shit-tastic trackpad was way, way better. But of course I just did what a lot of PC laptop owners do and ended up carting a mouse everywhere (I'd have to have the power brick anyway, and once you're in "I'll need a bag" territory you may as well toss the mouse in)
