It really helps if you set up your environment to mostly not need accurate clicks. For example, avoid needing to grab window title bars or corners, use keyboard-driven window managers. Use keyboard commands instead of clicking buttons. When I last used a Thinkpad, the only time I had to aim at all was clicking links on web pages. I still used the trackpoint to switch active window, but it was a "shove toward upper right", not aiming the pointer at anything (I liked the spatial aspect of it, compared to keybindings).
I also had it configured to move significantly faster on strong input, and slow down with gentle input.
The way I have my trackpoint set up (low sensitivity, no acceleration) makes it more accurate than trackpad, even. No acceleration means it always behaves extremely predictably; for me it's most useful when typing in forms and clicking around in them. It's extremely accurate and useful when set up properly. You can make tons of fine, precise movements and clicks when filling out documents and forms without even needing to move your hands from the keyboard.
Low sensitivity and no acceleration means it takes a very long time to move from one side of screen to the other. I guess I really don't fill in many forms where I can't tab between fields. But many of my habits also predate mainstream availability of GUIs...
Force yourself to use it exclusively for a while, no cheating. For better (it's great) AND worse (you have fewer options for laptops), there's no going back after that. I love it and even use Trackpoint with my desktop computer.
I used a couple variations for about 2 years - Thinkpads with a red trackpoint thingy. never liked them. Continually felt unnatural and clunky. Mac trackpad was a game changer for me.
Are there any hot-swappaple mechanical keyboards with a trackpoint? The only mechanical keyboard with a trackpoint I can find is the Tex Yoda II, which isn't hot-swappaple, and is also very expensive.
