Re: [off-topic] E-readers and Org-Mode

I am impressed, but I still believe that UI optimized for e-ink may be 
more convenient for specific tasks involving org files than generic 
Emacs build for Android. Perhaps conversion of handwritten notes to text 
should be delegated to a laptop or a PC.

I see that definitely it is possible, but I am unsure it is more 
convenient than OLED or LCD tablet. 4 regimes for screen is an indicator 
of some complications. Choice of Android may be a way to avoid 
development of custom UI. I have not checked if it is possible to build 
custom Android variant, unlock bootloader and still get comparable 
performance.

Where was a period when LCD monitors were slow in comparison to CRT ones 
and people complained concerning annoying trails on dynamic images...

There is no reason to install high performance CPU if the goal is to get 
time between battery charging noticeably longer that for regular 
gadgets. Highest refresh rate means 5W power consumption in the case of 
PineNote.

It is not apparent for not-ereader, but I see the same black and back 
flickering magic to fight with ghosts and to achieve uniform background 
with high contrast on remarkable. My impression is that change in time 
to pass whole cycle is not dramatic. Likely long enough pause is 
necessary to let particles orientation to settle.
