Check out what Zubersoft has done with their sheet music app, in a special edition for e-ink. https://zubersoft.com/mobilesheets/forum/archive/index.php?thread-5285.html https://zubersoft.com/mobilesheets/forum/archive/index.php?t... The kicker is this: “- Freeform annotations with the stylus utilize special rendering on Boox devices allowing the drawings to show up in real time. This makes it much easier to write and draw.” I use this app on a Boox Max Lumi and the effect is very pronounced. It really doesn’t have any noticeable delay, just like the “native” Boox apps. So, I think someone did indeed crack the code for fast updating.
