The original is in Eb - not the most Anglo friendly of keys - unless you have an Eb/something that is. OK for other systems, I imagine though my friends who play English system tell me flat keys are not their preferred choices.
A self-fulfilling prejudice? If they don't work with those keys, then their fingers won't become used to them. Well, this may have to something do with the sorts of music they play and the keys in which those melodies are usually played, if they don't explore beyond them. Myself, I have no more trouble with flat keys (up to 3 flats) than I do with the sharp ones (up to 4 sharps).
