Why iPad though? I’ve seen a specialized electronic music sheet (seemingly based on e-ink) in some videos, I guess pages are flipped using a pedal since I didn’t notice any visible interaction with it to do so, e.g. https://youtu.be/oB-gF2Ncphg
Also, eink screens are nice to look at but so expensive for non-kindle sizes.
chucking the ipad because of that is like chucking the baby out with the bathwater because the bathwater got cold. The baby still has value. you just replace the water.
