The people in this thread are nuts. I play music at a very high amateur level and know a lot of people with both absolute and perfect pitch. They all enjoy showing it off and are great sight-readers. It's a little more annoying for them to hear music at a less-than-professional level, but no more so than anyone who develops their ear to distinguish between subtleties in other parts of playing like phrasing or rhythm.

(Maybe that's less true for true perfect pitch, though.)
