I've tried that, unfortunately regular iPads are just too small for full-page display of musical notation. Actually right now I just prop up my MacBook Air, but then the keyboard sticks out, and similarly it only displays 1/2 page at a time, and so forth.
gotcha, that makes sense. You might be able to get a cheap chromebook with a big enough screen that folds into a tablet form. One thing to be careful with on these is the brightness of the screens if you want to use it outside.
