Hi I just received my 'new' g3 800 ibook ( got it as a closeout deal ) I have a couple of questions :- The keyboard has a lot of flex in it and feels really mushy.. ie when pressing keys on the right of the keyboard I can hear the thin metal plate underneath flex.. on lifting the keybard I find it is not toally flat.. ie has a small dent in it .. is this comon .. and do you think it it may be causing this mushiness.. How resistant is the case to scratches ? thanks in advance Paul
