As you say an eye for an eye, soon enough the whole world's blind. I find plenty of things in the Korg pretty stone age too. That's kind of the point. You figure out what you like, you figure out what you need, and you get whatever does the job FOR YOU best.
But no one makes anything technologically and sonically superior across the board.
Me, I tend to look for simplicity and convenience. Others look for micro editing and infinite customization. Others just want to hit the power switch and play without reading the manual..!
No one piece of gear is EVER going to please all three of us!
