Bookshop.orgβ β β β βA good place to shop online for books and still support indie bookstores. They sell eBooks too, in standard ePub format.
BOOX Go 7 Color (Gen II)β β β β β After five years, I replaced the Poke3 with the Go 7 Color. Itβs a lot faster and more responsive, brings back physical page turning buttons, and adds (pastel) color. Like its predecessor it has a sharp e-ink screen and runs any Android-based ebook reader app.
eBooks.comβ β β β βAn eBook seller with some actual business ethics. No hardware (which simplifies things), but they have an app for Android and iOS, and any DRM-free titles can be downloaded and read on just about anything.
Kobo (eBook store and readers)β β β β βA solid alternative to Kindle, from the eBook selection through apps and hardware. The app works well on my eink tablet without too much tweaking, though it still wants to sell me more books before I can open the one I want to read.
Onyx BOOX Poke3β β β β βI used the Poke3 as my main ebook reader for almost five years. Itβs a convenient size, has a clear e-ink display, and can run the Android app for (almost) any eBook store.
