Compared to the cost of just a magnetic strip, those fancy OLED or other display options are HUGELY expensive. All we are talking about here is a style 'Category' display, and you are turning it into a major upgrade problem.

Remember the time NASA spent millions developing a pen that would write in zero gravity, and the Russians simply took pencils?

Same thing...

There will nver be an arranger with magnetic strips...

Its not efficient, you will keep on loosing those despite their magnetic abbilities. Next to that it looks cheep on a $4000 arranger. And even if the developers think its a great idea, the management of those companies will make sure its never going to happen.

So, for the want of a nail...
