Excellent -- now if you were to share your newly learned insights with other ministers, a brand new market for the device might develop which would further increase the visibility for the devices.
And I would think that the publishers of books aimed at ministers and other religious scholars might be enticed to make their books available in reader format, further increasing visibility for the devices.
In any event, I'm delighted it works so well for you! It's a use I hadn't thought of, but will certainly consider for any occasions where I need prepared notes for public presentations!
