You sound very much like me, there Lou. If I imagine a note in my head from a recording which I know to be A440 - for instance the bass intro to Psycho Killer - and tune to that, then I'm usually within a quarter tone of the correct pitch. If a guitar's in tune with itself, though, it could be over a semitone out and I wouldn't notice! But my son, who's twelve, can and does notice. Bizarre.
There is a distinction between perfect pitch and absolute pitch. Perfect pitch is the ability to accurately and consistently identify or sing intervals given any start note. Absolute pitch is the ability to correctly identify a specific frequency, a 440hz for example. Very few people have absolute pitch, quite a few have perfect pitch.
