I have perfect pitch, I learn to play cello and violin, but I can play synthesizer, djembe, block flute and few other too, but not that good as the first two.
And of course I am one of those who have perfect pitch and AS:
I can say I am not very good at relative pitch, it's easier for me to guess the tone itself than in relation to another one.
And yes, certain sounds go on my nerves.
My anecdote about perfect pitch:
When I was tested if I have good ear enough to play the violin, they at first didn't want to accept me either, because I was too old (I had 13). Then, OK, they agreed.
I done everything just perfect, they told me.
And what is the most funny, when teacher played two melodies on the piano and asked me if they were the same, I told her she only changed F and F# note. She laughed.
I actually wrote an answer in WP:

Would be thankful if you'd answer my questions about perfect pitch in this answer
