Not quite that extreme. I could use it for harmonies if it wasn't too many dissonant notes because I couldn't tell the notes apart. However, that is something I trained before doing the perfect pitch thing. Being able to pick apart harmonies is extremely useful. Having perfect pitch just made it a little easier. I always found it hard on the piano. I wonder if it is related to the fact that everything sounds good on the piano, even things that are badly composed. Parallel fifths in a chorale on the piano? Sounds wonky but ok. In a chorus? Awful.
