Onyx Boox Nova 3 vs Onyx Boox Poke 3

I need an e-ink reader to use for reading at night before going to sleep and being able to highlight text and later review and amend that text in Word or Google docs. I also want to be able to continue reading on tablet or PC when it is not before bedtime. So why the Nova 3. It gives me 7

You're going to want an Android based ereader because the web browsers on "normal" ereaders tends to be bad and experimental at best. Androids have the possibility of side loading an eink friendly web browser that doesn't suck. The Likebook P6 was on sale pretty recently, and the Boox Poke 3 is another decent option—a 6" screen should be fine for Wikipedia.

I'm open to a device that is 8 inches or larger, and ideally has a nicer screen. Some options I was considering were the Galaxy Tab S7+ used (tough to find under $400), or going the e-ink route with an Onyx Boox Nova 3.

If you read a lot of manga & PDF, you might be happier with an 8" screen (so Kobo or an Android e-ink tablet like Nova Air or Meebook.). Bigger is better with PDF because panning & zooming doesn't work that well.

Its user interface is simple to understand, easy to use and full of unexpected – and useful – features. It’s divided down the spine into Library, Store, Notes, Storage, Apps and Settings. The Library allows you to read and annotate any kind of ebook, but more uniquely it displays book covers and illustrations in color.

It makes articles as easy to read as ebooks, and even though it's only been a day I just love it. The only thing I'd change is for it to have it's own search page rather than use duck duck go's screen. The browser has a page on GitHub though, so I should probably pop over and suggest it. Honestly, this browser has made it so I have started reading internet articles on my ereader, rather than my phone, which was one too painful before even though that's one of the main reasons I bought the Boox Poke 3
