well i have a new iBook G4 along with my sister and i noticed that her keyboard taps are a lot softer than mine, mine are louder and you can hear it click more. I was curious so i looked at my keyboard and then looked at my sisters and she has the rubber in between all the key which makes it quiter, just wanted to kno if anyone elses iBook is like this because mine is just connected with the metal piece then the actual key, dont know if this was a mistake or something....
