It seems alot of folks DEFINITELY need and prefer the button access over the touch screen- and quickness/surety in live play is a big reason - so I'd guess valuing the G1000 a bit higher for live play depends a great deal on how quickly you need to move between tunes?? - nature of the music, the audience mood shifts, etc.... I go slow

For myself - I enjoyed the touch screen of the Triton I had briefly - even if Korg is a little page intensive. Nothing perfect eh?
