apparently most of the keyboard players out there do. the fantom G is a self contained workstation where everything you need to do production wise is within the unit itself. Same for the Yamaha XS, and the latest Kurzweil. Musicians like options and if you have learned to create music with the instrument you make music on it can be really hard (and uneccessary) to have to adapt to making music with a computer attached. I make all my music with just the PA1X and because thats the way i work i can produce and write eficiently and seemlessley. That way the technology works with me and not against me. If the workstation elemnet was taken away from my arranger i woukd be stuffed creatively.
