I never was able to learn how to read the dots and play too. However, I can read guitar tabs, which I'm told is more difficult. In my case, I use an Acer Aspire1, which has a small, inconspicuous screen that my audiences rarely notice. It's used primarily for lyrics, and an occasional MIDI file using Van Basco.

Cheers,
