A cool thing to note is that you can't read Kindle "Textbooks" on any first-party Amazon e-ink device but you _can_ read them on a Boox e-ink device precisely because it runs Android (read: eTextbooks are supported in the Kindle Android App but not native Kindle devices).

Not to mention you can read other textbook-like sources on e-ink like O'Reilly Books and Scribd as well through their Android apps.

I was trying to use orielly app but it doesn't seem very good on eink. Has crazy amount of ghosting.

I was going back and forth between lumi and air. Are you finding bigger screen more useful for reading tech books?

You can turn on paged reading rather than scrolling (and fiddle with some of the other settings around color conversion which had bad defaults) and it's as good as any other app.

I read an endless stream of academic papers, which why I opted for the lumi. Most textbooks are less dense (in my experience), so would probably be fine on an Air.
