The HTKB keys are definitely firmer than the USB KB but not up to IBM laptop standards-- none the less, much better than the USB IMHO. I wouldn't call them clicky but I'm not sure exactly what you mean by that. I haven't used the USB KB in so long I can't even remember the layout. My main gripe about the HTKB layout is the backspace key is small and poorly placed (just don't make mistakes!-) and the pointstick has a way of getting hit in mid typing so that you end up moving the cursor in mid word. I never had this problem with IBM pointsticks. Overall I think the HTKB is acceptable for use on travel and in your lap and much better than the USB KB but I'd recommend a real keyboard for extensive input if you are deskbound.
