Good. E-ink displays are expensive and have a monopoly on low-energy persistent displays. However, Rdot doesn't have nearly the same resolution as E-ink at this time, it seems: https://rdotdisplays.com/technology https://rdotdisplays.com/technology

Their FAQ says they are planning on offering matrix displays next year (https://rdotdisplays.com/faq https://rdotdisplays.com/faq): > We expect to introduce an entirely printed passive matrix version in 2019. It will definitely help to have some competition in this space.

The contrast ratio of 3:1 isn't great either! The first generation of e-ink had a contrast ratio of 7:1, and they've been at 15:1 since 2013. [1]: https://wiki.mobileread.com/wiki/E_Ink_display https://wiki.mobileread.com/wiki/E_Ink_display

  1:3 for the grey version. But the RGB versions do much better: Red: 1:8 Green: 1:11 Blue: 1:7 https://rdotdisplays.com/technology https://rdotdisplays.com/technology

Well I'll be damned. I thought kidles were cheap but you can actually get a Kindle 7" fire tablet which does a lot more for 50$ and a Kindle 6" eink reader is 70$. So yeah, I'd have to agree with you, some competition would be nice

  I wouldn't recommend any of the current generation kindles. I've been gifted every single Kindle there is, and I have to say that $50 is not worth it unless you really just want a throwaway tablet as an alarm clock or something. It's cheap for the following reasons: 1) you're stuck inside the shitty Amazon App store ecosystem. Lots of developers hate that Amazon created their own separate app store, so expect no major apps on the download section of your kindle's app store. Especially not Google apps like YouTube. Just the lowest quality of low effort apps made by foreign developers. 2) screen and speaker quality sucks now compared to previous kindles. The UI and user experience has just always been bad because you don't get anything resembling stock Android OS. You have to use whatever weird skin that Amazon decided to tack on to their weird and limited version of Android. 3) the tablet's price is subsided by ads. It's cheap because you have to see a different ad every time you unlock the Kindle screen. The kindle's speakers used to sound amazing on the old HD, I forgot what it's called but it was the best tablet Amazon ever made. Every Kindle ever since has been significantly worse. Id you want a tablet, find some $80-$100 Chinese tablet from somewhere that can at least doesn't blast you with ads. It's worth it.
