isn't that exactly what E-Paper tablets are really good at?
I would love to use an e-Ink screen, because they play much better with stage lighting.
However, I’ve yet to see one that can do what I want the iPad to do, sheet-music-wise. I don’t only want to see it, I want to be able to make markings, scan scores, act as a pitch pipe and metronome, have an onscreen keyboard to plunk out the part I’m singing if I’m struggling to read it, etc.
Edit: Realistically, I could use my phone for the scanning, pitch, metronome, and keyboard. But I want to be able to quickly make markings and the iPad shines at this, especially with the app forScore.
(That also isn’t the only thing I use my iPad for, just the main excuse I have for owning one. I actually probably will buy the M4 Pro, but mainly because I already have a buyer for my current iPad and because it’s so much lighter.)
