This is a really unfortunate move by Amazon. My next e-reader will be one that I own (instead of just rent).
Glad that I took the time to jailbreak and pause updates on my 2017 kindle paperwhite while I could.
Their main advantage is providing access to all e-reading apps available on the Google Play Store, including Amazon's own Kindle app, as well as sideloaded ones such as KOReader.
On the downside, the battery life on those isn't as good as that of dedicated Kindles, Kobos, or other lightweight e-readers, but they still hold a charge for four or five days if one turns off their antennas, which is plenty of time to recharge them.
As for the ebooks themselves, I switched to purchasing from Kobo and other ebook stores. Some sell DRM-less ePubs, which is nice, while those that come with DRM can be easily liberated. And for the occasional Kindle-exclusive that is struck with (temporarily) unbreakable DRM, the Kindle app, although annoying, works well enough.
Also hearing good things about XTEINK X4.
I really appreciate that the company that makes the device has embraced the community firmware scene and even links directly to them from their website as a semi-blessed alternative to their official one.
I do miss physical buttons a little, but that’s minor gripe.
I struggled with reviews when buying as I do love having a local library and the ease/difficulty of setting this up is never in device reviews.
