29th century PADDS are, I think, used more to study the effects of chronitons on a sentient being. apart from that, I don't think the border does the PADD justice. You should consider removing it or making it substantially smaller (compare to Relativity's consoles for that).
I'd still give the holographic one a try. Don't forget that FutureJaneway used a holo-emitter to show a Borg too. And, ofcourse, the whole fact that there is the holodeck in which a person can manipulate an image. Holographic is the future
