Hi, I am professional organist. I play concerts, funerals, weddings....etc. i was thinking about using an iPad for all my music scores. Do you think the iPad with Forscore are solid and reliable enough for a concert. Funeral...etc? Would it be safe to leave all my paper scores at home? One last question, if I am just going to use it for my scores, email and some games, do you think anything better than a refurbished iPad 3?
