99.9% of Arranger players are home players, (Pro players hardly register) who because of a day job or other interests cannot devote enough time to achieve 12 hours a day practice, so like having the instrument do some of the work for them to give them inspiration and happiness. (Also everybody is different in what they want from a keyboard, and the resources available to them)

If you look at the poll, it is about the instruments, not the player.
