I would think the main reason for preferring the UHK is the capability to add the trackpoint module to it, even though you gloss over it in the text. :D.

Btw have you tried the trackball? When they introduced the modules I was vacillating between that and the trackpoint, but ended up with the trackball (of which I'm very happy), but I would be curious of alternative points of view.
