Nowadays the term "Workstation" is different than it was back in 1992. I consider a workstation to include a synth or & sample playback engine, MIDI and audio sequencer plus a CD-R so an entire MIDI and audio project can be finalized on the one machine. I'm not saying this is better or worse than a computer based system, but for many musicians, not having to depend on a computer to produce a CD can be a huge plus.
And I have changed my mind about so called "home keyboards" after hearing the ketron SD-1 and Yamaha 9000 Pro. The new Yamaha Tyros also sounds very realistic from demos I've heard. As Pilot says, PSR keyboards are usually just based on current chipsets that are used in other products. I like the auto accompaniment feature in home keyboards which is really just a useful enhancement of a usually static MIDI sequencer. You can create your own styles which can make auto accompaniment a useful song writing tool. Unfortunately I haven't yet used a Yamaha MIDI sequencer that is conducive to creativity.
