4. Are you able to read colored book on it? Now, I know it's a white and black screen – but, does the resolution and amount of shades of gray enough, or you turn on your tablet every time, you're reading a colored book? Say, a medical anatomy book?

Short:
2. Yes
3. Very long I have charged it only once so far
4. Yes, if could you provide a specific example I will send you back a picture so you can judge yourself.
Long:
2. I don't like this app UI but it work reasonably well. First experience was horrible so I thought the reply to this question will be NO. This device is very slow, it is only single core 1GHz cpu. While it is still a lot of computing power most apps today are developed and tested on much much faster cpu, at least dual core, typically I would say quad core 1.5 GHz. This lead to some occasional quirks where your app display "application is not responding, do you want to close it? WAIT, CLOSE". Kindle falls into this category. The first time I started it I saw black screen with Kindle logo and nothing happened, I taped a few times WAIT for the popup but eventually I let it CLOSE the app. I tried again, being patient, and another time and finally I got into a new screen where I logged into Amazon, but then again the experience was horrible until this stupid app finished downloading a ton of something and started to respond to my input. From this point the app works fine, quick enough. There was one more thing to change: every new app installed gets 3 enhancement options enabled by default. You can access them by long press on the app icon, and choosing from the menu "Apps Optimize Settings", you want to uncheck the option "Enable Contrast Enhance" for this app as it makes the fonts too crisp.
3. I connect it from time to time to my laptop which charge the battery. You know, recently I have been developing the app ReLaunchX. In addition the default settings of the device are screen lock timeout and power off timeout, so each night (and day..) the device power off itself.
4. I bet the shades representation are not linear. For me it looks ok for viewing colored books but if you really depend on differentiating certain shades (you mentioned medical usage) it may be the case that those shades will blend together with closer ones. I don't think the CARTA display is any better for that, these displays are not designed for medical or graphic design use.
Some additional rants:
The apps provided by Onyx are excellent and very fast on the device: OReader, Neo reader 2.0. Kudos for Onyx team for such good development.
The screen is really good. Given that I do not have to read 1 millimetre size font the resolution is good. Contrast ratio is also good. One catch is that web pages and modern android apps (android material design) like for example the Google Play store never use black fonts and avoid high contrast in the app in general. This makes them look washed-out on this ereader. I don't have any other ereader with Android so I cannot compare if it is typical. Kindle app also looks washed-out but once you open the book for reading it display the font with full contrast.
This initial effort to start a new app happens quite often. It looks to me that most of the apps do a lot of things when they are started for the first time. Then any consecutive start even after power off/power on is normal.
Occasionally there are some problems with visual feedback. You press a button in some app but it is not registered at all and nothing happens, the other time, you press a button two times still nothing happens but suddenly the action is done 2 times (the annoying outcome is when you tap that way on some back button). Other times the screen seems to display not current content from the app, you need to tap somewhere to make the screen refresh when you suspect that the screen is not current.
