Yes, I'm one of such hearing impaired person :-). It has many
advantages for composition, silent reading music scores and
leadsheets, sight-reading, improvisation, study from hearing, music
analysis in real time, converting audio to written score...

But transposition can be a real problem, you are right. I've never
used transposition feature on my instruments :-) It's confusing to
play in Db major and hear F major when instrument is transposed, or
to do transposition in real time when reading the score, like to play
the score written in G minor and play and hear Eb minor, for example
(sometimes singers ask such thing). In such case it's more easy to
play without score.

Few months ago I've got newly made double manual harpsichord, copy of
Flemish Baroque type, for my concerts and studio recordings, and
alas! - with Baroque tuning A=392 Hz. That means whole tone down, A
sounds as G. So I fight with it right now. To read and play score in
B minor and hear A minor is rather confusing... Even improvisation is
not so easy, to press C key and hear Bb... So I will perform without
looking to the score, and completely forget about visual. But tactile
problem with different sound on each key is still here...

This is the only disadvantage of perfect pitch, there are more
positive aspects for musician I would say.
