I'm by no means and expert but I have had several Korg arrangers (Pa800, Pa2 XPro, Pa3x, Pa476, I've had Tyros2, Tyros4, Tyros5-76, PSR 3000, S900, s910, s970). The only problem I ever had was reading outdoors in bright sun, but where I played outdoors they had a canopy so the problem was solved. Seems to me no one has laid hands yet on the Genos but some are saying they have issues with the fixed screen, how do you know it will be an issue?

Maybe it's because I'm young and have good vision that I've never found it to be a problem?
