As i understand they have put the internal mic on the pro version under the left speaker grille. Why on earth? Again? (on the Powerbook it was next to speakers and keyboard to) Why couldn't they put in next to the cam as it is on MacBooks. I mean what good is a internal mic (supposedly easy to use allready integrated feature) if it is next to your vent with the sweetest buzzing sound. What the !"#%& am i gonna do with that?? I even can't type the same time i'm talking to my friend because the mic is almost under my keyboard and you hear every touch. Oh, and dont forget the echo your friend hears when you do not use headphones. Nice work apple!
