I agree with Uncle Dave. I myself do at least 400 - 500 gigs a year. Incidentally, I have a great setup:
My PSR2000 with 2 sustain pedals, adapter, music stand, floppies, and headset microphone in a vinyl gig bag. A folding keyboard stand. These two go on my luggage cart. On my shoulder I carry a duffle bag with two Advent Powered Partner speakers - 8 lbs. apiece. I can arrive at my gigs eight minutes before show time and set up in time.

The Genesys looks like an amazing machine. Now if the 50 lb. Genesys had modest monitors plus two powerful speakers facing the audience, I would be interested. But the Genesys speakers face directly toward the musician. This keyboard was made with the studio musician in mind - not the gigging musician. At the same time, many studio musicians are using their computer with their computer's CDR drive to make recordings. I don't think you can beat a software like Cakewalk for MIDI sequencing - especially when you have the advantage of a 19" screen. So the Genesys is really made for a small niche - studio musicians who are computer phobic. The gigging musician is inconvenienced by the weight of speakers facing the wrong direction and the computer desktop musician is paying for sequencing capabilities and a CDR that he doesn't truly need - not when there's a hard drive and SCSI or USB.
I hope GEM comes out with a scaled down version of this monster, much like the PSR2000 is a scaled down version of the PSR9000. If they do, I'll be checking it out.
