Hello - When I click on the built-in mouse (whatever it's called), it's a lot louder/snappier sounding and feeling - makes more of a loud clicking sound - then my old Powerbook G4 did. Might I have gotten one that's a little out of whack or are they all that way? If it's normal, why so "clicky?" These days aren't they able to make things softer/quieter? I also noticed how sharp one of the corners is in the area where the latch (or lack of) is...that center area where you lift up the lid. I like that much better than the old one but does anyone else have the problem of a corner being too sharp? That's all for now - thank you!
