The last I checked (a few years ago), there were two versions of the ThinkPad stand-alone keyboard (old, and new). The ergonomics differed enough that there were plenty of comments on this. So, when looking at information on it, make sure you know which revision the person is talking about. I seem to recall: + Differences in the flexing of the keyboard + Differences in the "wrist rest" shelf in front of the keys. + Perhaps some differences in keys / key placement / layout. But it's been a while. (I never ended up buying one, myself.)
