Just got new MBP 13" yesterday (nice mirror, btw ). I've noticed that top part of the touchpad (aproximately 1.5 cm) doesn't "click". So when I press everywhere else - there is noticablee click - how it should be. But not the top part - it doesn't click no matter how I press it. Is this correct how it should be or my unit has problem? I can't remember if I saw this in the Apple store..
