The purpose of a display has completely evolved since the '90s.
It is no longer aimed solely at the person standing in front of the flippers in a dull red or orange, but to draw attention to other surrounding people with the use of full colour, preferably high resolution and large screen graphics and thus convince them to choose this machine to sink some coin into over its outdated neighbour.
Just about every piece of modern technology these days focuses on screen oriented (or at least is very heavily emphasised) tech.
Any company which doesn't embrace this philosophy is going to remain technically obsolescent.
Btw I didn't look at woz screen during gameplay once.
But I bet anyone standing around you in the vicinity did. Happens every time I have a meet when someone is playing WOZLE.
And as soon as the game ends one of those watchers then becomes a player by wanting to have a turn on the machine.
JJP nailed it in that regard.
