I’m a converted guitar player to arranger player and weight is a big issue. At my senior age, that’s the first thing I check on any new product or potential purchase. What it looks like, how it sounds, and the cost are all secondary issues. And, if indeed, arrangers are pitched largely to us old fogies, as some have argued, then you’d think the manufacturers would be keenly aware of the weight and size issue of their keyboards.
I'm a converted guitar to arranger player as well. And weight/size issue might be in part what is driving one of Yamaha's new MOTL arrangers:
