Is it just me, or is the keyboard on the new iBook (I have a G4 12 inch 1 GHZ) really difficult to remove/replace. I had a lot of problems with it jamming (even when the num-lock locking mechanism was completely unlocked). I finally discovered that if you press the keyboard's bottom notches FIRMLY into the slots in the casing before lowering the top of the keyboard, it lowers/reattaches properly.
Although, after doing it this way I notice that the springy clip things at the top really don't clip into the case by more than a millimeter. I can see part of the little piece that is supposed to slide in to the case on each clip, and I seem to remember that this part was completely invisible (slid into the case) previously. But they keyboard seems held in quite well now, and raises/lowers very smoothly.
