    I use an iPad Pro for my symphony, chamber music, chamber orchestra rehearsals, and concerts, long pieces. There were two instances where I barely made it to the end of the concert and anxiety re: running out of power is something I don't need on top of working through a R. Strauss tone poem, Mozart violin concerto, and Mahler 5! The product works very well, so all I have to worry about now is playing the music!
