I think Korg's are highly overrated. Once you turn off the effects processors, most Korg's sound dry, stale and uninspiring. They depend on effects WAY too much...
Most Korgs (Triton, Trinity, X series, N series) are pretty much a 01/W or M1 with newer waves and other bells and whistles - no real innovation there. I know, I own a M1r and the X5D.
