The thing is, Eink's waveform is kind of secret afaik, everyone has different tuning.
We had some secret eink sauce (propriety waveforms) to get the high refresh rates and colour contrast without a full flashing screen reset, but even then you need to run longer maintenance refreshes occasionally.
Pixels are just vertical columns of viscous fluid with charged ink particles. A waveform is just voltage changes over time to these columns to shift the particles up and down. More black to the top = darker shade of grey. Colour (in the gallery display, at least) is the same, just with each CMY particle group having different charges and responses to different waveforms.
Every once in awhile this vertical column gets messy with loose particles distributed through it (ghosting, muddy contrast) so performing a hard rail-to-rail voltage reset forces all the particles up and then down, and gives you a clean slate.
Versus someone drawing on the screen with a lot of zooming and panning. People with the tablet would notice that when they stop a series of these actions that were back to back, the screen will "clean" itself after about 5 seconds of idleness.

I'm guessing you could probably push that somewhat by going beyond the specifications, would wager a guess how far though.
What would you suggest instead?
A better way to look at this is valve is trying to hedge it's self against microsoft. By creating an ecosystem of devices and software that's full open so they're not reliant on Microsoft. The goal of Valve hardware ISN'T to make money. It's to encourage others to build devices free of Microsoft that Steam can be installed on.
They have nothing to gain by being closed, and everything to gain by being open.
Steam has been an incredibly good steward of its position, but I fear for the day when capitalism finally sinks its claws into the platform.
Capitalism has nothing to do with short term greed.
Some CEOs are just too arrogant and think that optimizing for the short term won't hurt goodwill. That's their own failure. Capitalism says nothing about how a business should be run. It's merely defining the idea that humans who own things (capital) allocate their resources and keep the result.
Regulation can also break things if done incorrectly/poorly/inefficiently/corruptly.
Check it out here: https://github.com/xfoa/humours. It's not finished yet, but the basic functionality works. It just has one widget at the moment that draws a spinning cube with temps, etc.
On the other hand, you probably don't want that glow of an active screen all the time. Status LEDs are annoying enough.
My kindles usually show a dead battery graphic when I get back to them after a long time away... With enough power storage and the right trigger, this could be done.
Too bad. The picture in the articles looks awesome. Like a device from some alternate reality. Neither retro nor the standard flat-panel LCD.
I don't want to mod a pre-build $1,049 device. I want it to be good our of the box and I'd rather pay more to get more. (If it was a $3K top-of-midrange machine, I would buy it in a second.)
