Targetted devices are latest top tier models ereaders and these happen to be Kindle Voyage and Kindle Paperwhite 3.
The ereader market for anyone like me that wants to maximise the epaper beyond pdf/books(decent web browsing, external hdmi/mhl/DP... monitor) usage is very stagnant.
Difficult to read article from goodereader on the subject of epaper innovation(or lack of it).
All ereaders use the same(and limited/dated on arrival) hardware with freescale CPU's 1GHz(1.2GHZ on Onyx Carta2 device) and 512MB DDR RAM.
Meanwhile tiny, powerful chips like the Qualcom 810/820 and Intel Core M
with excellent RAM specs are being fitted on tablets, PC Sticks and the like.
There never will be a native and meaningful android/windows/ios/mac or linux experience on an ereader(for those that value their vision and enjoy the greater outdoors) until eink and EPD controller board manufacturers are so limited in their focus - low powered devices.
Just to prove eink is not limited by nature to that please check this eink monitor showing animation on a USB Eink monitor(Dasung Paperlike 13.3")

Eink development boards via visconnect and digikey don't have the specs I talk about or the price point needed.
Dasung Paperlike monitor is still beholden by the same hardware and must be using a lower spec cpu Freescale i.mx6 at about 1GHz.
Kindles once rooted can have access to the entire OS.
The idea is to use a modern hdmi spec intel compute stick like dongle(gen 2 Core M reads good) that ouputs hdmi signal that is then hdmi received and
bandwidth reduced for partial updates etc
Kindle voyage / paperwhite 3 mod that lets them be used with any PC Stick really.
Here is a Freescale HDMI input enabled board

This is all sketchy so here are the
Good points :
Underlying OS is Linux/Android based
USB socket is already present on Kindles. So an HDMI out to a kindle USB "DIY GPU" adapter might be capable of delivering the grayscale bandwidth to the Kindle OS directly.
Kindle Touchscreen activity may be Kindle OS monitored and forwarded by USB/Bluetooth to the PC Stick OS(some Windows 10/Android mouse drivers might be needed)
All this is to be done on the Kindle's 1Ghz CPU and 512RAM.
Making a mod to turn a Kindle to a responsive touchscreen monitor would require a good "hdmi input from PC Stick to Kindle USB- output" diy device. The device would scale the hdmi stream down to grayscale and compare for screen regions that have changed and need to be updated on the kindle.
Lots of energy wasted on scaling down from HDMI input but with Dasung Paperlike asking $995 for essentially grayscale eink USB monitor that's near impossible to buy.....
Ultimately a tiled display wall of kindles is what I am after
