In reality, many instruments are geared toward home players - including pianos. If a piano were designed for someone that is constantly on the road, it would be made of a lightweight, very strong, space-age fiber so it could easily be moved from one locations to the next, yet still provide the warm sounds of a real piano. However, pianos are more a piece of beautiful furniture, exquisite woodwork, incredible craftmanship, matching bench, and weigh a ton. So, in reality, the arranger keyboard is geared more toward a pro musician than a real piano.
What makes it a pro instrument is the person playing it - not the instrument itself. The arranger's many, many features are rarely used during an actual performance. Lets face it, no one is going to edit a style or voice while performing, they might record part of their performance if they happen to think of it, but in reality, today's arrangers ARE professional instruments and played by professionals. What would make them a home instrument is when they are played by home players. At least that's the way I look at it. Same with guitars, saxes, trumpets, drums, etc...
