It can look good [1] but I haven't yet seen the refresh rate of eInk that I thought could handle a moving cursor. Maybe with the right driver you can these days.
A machine with the 12” Macbook form factor and an e-ink display with optional orange glowlight for night running something akin to Classic Mac OS would make for a very zen, highly portable writing machine. Would probably get battery life measured in weeks, too.
I'd be glad of a contemporary device w/ a b/w LED --- still saddened that there wasn't a replacement for the Asus Eee Note EA800 --- and I'm still annoyed that Apple has yet to make a device to replace my Newton (at a minimum, I'd want Apple Pencil support on an iPhone (or iPod Touch if they'd bring that back) or Mini iPad), but using something other than an LCD for daylight viewability would be something I'd be glad of (trying to out-bright the sun on a battery-powered device is just as stupid as it sounds to my mind).
