I get excited about different laptops occasionally...and then I remember that I won't have a trackpoint if I switch to a different brand, and I get disappointed. Literally happens every few months.
I think they were competitive with old touchpads (and probably the ones you still get on cheap laptops) but I expect all the people above praising them have just never used a modern Apple touchpad. Far superior. It's not even close.
There's a good reason nobody makes them anymore.
I suppose a trackpoint might be useful if you really want your hands never to leave your keyboard, but generally I'm either editing text with emacs keybindings (where I don't have to use the mouse), or else I'm in a mode where having one hand off the keyboard doesn't feel at all hindering.
Maybe I could be convinced, but since they're hard to find these days and getting harder there wouldn't be much point (except to frustrate myself on the off chance I ended up loving them).
They don't have a learning curve in the sense that it's difficult to make one functional, but when I did try a trackpoint I felt it terribly awkward and imprecise. I'm not at all surprised that there would be a transition period after which trackpoints at least felt better to use.
They do have a learning curve; but FWIW, I feel exact the opposite - I can achieve both lightning fast movement, AND pixel-perfect precision with the trackpoint (the latter I have never managed to consistently achieve on a trackpad).
(Note, for me, it's never a "Trackpoint vs Mouse". I'll use mouse 100% of the time when at my desk. When not at the desk though, it's "Trackpoint vs Trackpad", and for the amount of space it takes, the compromises it instills in keyboard layout and ergonomics, Trackpad never quite worked for me. On aside, I miss the potential of netbooks because a 10" screen with Trackpoint would be a formidable hyper-portable machine with today's ARM processors - but not if you need to reserve 5 inches for a trackpad :| )
But they do. Last I checked HP, Dell and Lenovo all had options for power users (not in their consumer / mid-range laptops though). Or at the very least, my last several and current clients have all sent me laptops with a Trackpoint from those three brands (and not to my asking; it's just fairly standard for mobile employees or enterprise customers to have Trackpoint included)
>>What learning curve? Isn't it just a joystick mouse?
well, no - to me, that's an inherent contradiction: Mouse and trackpad are both positional (as largely is trackball). Joystick, trackpoint are directional. They are fundamentally different paradigms.
In terms of learning curve, I do believe Trackpoint is less intuitive for most users, as it does have that different paradigm. I think it takes a bit of time to get really good at it - most people who use it for a few minutes feel it's inferior and clumsy. But I've had "races" with my colleagues with Macbooks, and spoiler - I'll agree it's not even close, but not necessarily in the direction you might expect 0:-)
(on aside, I do have a Macbook, it's about 4 years old. How new does a modern it need to be to fit your definition of a modern Apple Trackpad?
And I'm ready to admit I am not an expert on it; my point is exactly that I am an expert on track point and it's awesome :-)
