There are mp3 players available that feature LARGE BUTTONS, you would save money and hassles over getting a laptop just for that reason.

I know one guy who uses an mp3 player designed for Toddlers, simply because the readout screen and the buttons are huge. Looks kinda funny, but it sits on his music stand and the audience can't see the big colorful PlaySchool like "toy" he's using.
