Well, ive been starting to notice that there seems to be some sort of adhesive material right under the speaker grills on my TiBook, because dust stuffs are continuing to build up in there, and i cant get it out with compressed air, and barely have any luck even poking the dust out with a poking device! ...which leaves me thinking that theres some sort of sticky substance right under there, wherever there isnt an actual speaker or the small microphone pickup. mine is a 1ghz model, and i also noticed this on a friends earlier revision model [either 400 or 500mhz, cant remember]. anybody else have this problem or any suggestions? id like to try and keep this thing looking like new as long as possible, and that dust build up in my friends TiPB is rather uncool looking. thanks ahead of time!
