They include it because people use it. I actually disable my trackpad on my thinkpad, and only use the trackpoint. (So does Randall according to that link). Thinkpad keyboard is in my opinion better than the apple keyboard.
Agreed. I just joined a company where Macs are mandatory, and so I'm reluctantly making the transition from Linux/Thinkpad to MacOS/Macbook.
I'm experiencing substantially more carpal tunnel issues because of the Mac's trackpad-only setup. The trackpoint means I never have to take my hands off the keyboard, which I love. Two months in I'm used to Apple's keyboard, but I don't think it's as good; my error rate is still much better on Thinkpads because the more sculpted keys make it easier for my fingers to know where they are.
And I should say that here I mean the older Thinkpad keyboard, not the newer one that looks much more Apple-ish.
