In church, we need a pianist when we sing a hymn or for choir but with iPad or Galaxy pad, not any more, IMHO.
Here is my thinking.
On the pad we display notes with 5 lines or 11 lines. we just touch the notes on music sheet with your finger, then iPad will play the notes. You don't need to hit white or black key, just notes on the sheet which is diplayed on the pad. You only hit the notes with proper beat.
With this App in your pad, you can play quite any music with simple training. But I don't know this app is already on the market or not.
I think piano is required only for recital or for profesional.
In a small church, a pianist and piano is quite too much.
