Mind you, this is against anomalies: E-Ink's EPD has a delay - to the best of my knowledge, 125ms is the current minimum achievable. Then, the software may have delays - reasonable ones. I never measured them.

That's OK, but the device should be smart enough to detect that it's charging and switch to maximum CPU automatically. This is what happen on laptops. In addition, I suspect that an application optimized for e-ink, built with the manifacturer SDK, could be much more responsive than a general-purpose app written for regular smartphone/tablets. It's so bad that nobody wrote even a simple text editor AFAIK. I would use much more a writing application than the pen-writing notes.
My 2 cents.
