What point are you rrying to make.... That using ipads on stage makes you a bad player?
Not at all. Only YOU can make you a bad player. To me, standing on stage scrolling through an iphone (in Gary's example) for five minutes, is more detrimental to a performance than just saying "we don't have that song prepared, could we do another for you" or something like that. JMO. Don't get upset.
