Interesting. My wife uses her iPad almost exclusively for sheet music, with forScore for sheet music and GoodReader for PDF's as the main software. She plays flute and is classically trained, so she needs dots on the page. She even just got the new big iPad, and just loves it. I am still firmly in the paper / binder world myself, but freely admit to being a dinosaur. Most of the time, I play by ear and can hear and memorize chord changes and sequences, but as I get older more help is needed with remembering the lyrics.
