I think that today, with the new technology, the name of workstation means software and hardware able for people to manipulate or modify/work on sounds, mixing, loop, sampling sounds, etc... Fantom X is a workstation as the same as Motif. The capability of "workstation" is better than the keyboard with which one you can play direcly for a great pleasure as Organ Yamaha Stagea or Atelier from Roland. Just put the button and play! For my opinion, a G-70 is a playstation, not for working as I said above, even it has a sequencer. I think that Roland can change the OS for adding the capability of reading mp3 or something else with 40Mb left inside.
