Maybe it just me but...
Weight doesn't bother me. Maybe it's because years ago I used to fill an entire Dodge stretch van with my keyboard rig that took about two hours to set up, so I'm used to it. But mostly I think it's because I am concerned with quality and dependability. In my mind, quality and dependability starts with the construction of the instrument using the sturdiest of materials like metal. That adds weight but as far as I am concerned, that equals a truly professional instrument. Not cutting on the plastic instruments out there, I understand that 50 pounds can be real hard to impossible for some folks to move around. While others came to a small arranger keyboard from accordion or organ so the weighted keys are a hindrance. That's fine. But I for one am very grateful that Korg produces a professional grade, 88 note weighted action arranger/workstation.
