BTW, I want to point out that that was with the Dual USB iBooks (G3, not G4) So I don't know how well a G4's would fit. I heard they redid the key clips after the G3 line to work better with the PowerBook G4 series (instead of producing 2 types, they did one type of clip). Also, the G4s were easier to clip on to the keyboard vs. the G3s. it didn't take much to reset a G4 iBook's keys compared to the old Dual USB G3s.
