I use an iPad for some of our shows, not for chords or music but to give me cues for the words!
I use the iK BlueTurn footswitch to flip pages mid performance which reduces the visual impact for the audience and makes it an excellent tool on stage. I bought a special bundle which also included the mic stand holder:

A good tip is to buy a longer than standard lightning cable so you can have it powered all the time. A regular Apple cable will do but limits where you can place it and the power strip in relation to each other.
