It does support pdf. And I have no idea how your digital editions work, so can’t answer this one. But if they run in a browser, as an Android app, or if you can download them, they do work. Pretty much every e-reader now has a web browser, many of them run Android, and ALL of them can open downloaded files in a bazillion of formats.
Then download the app, geez…
That being said, e-readers come with quite good software out of the box, so even if they don’t run Android, there’s plenty of configuration options.
Oh, have I told you e-readers also support PDF? Oh wait, I have. Why are you still whining about PDF?
It runs all the apps on Play store. What else do you need? I mean seriously, please get down on the ground. It’s an e-reader, it’s not supposed to replace your PC. Or your tablet. Or your phone. Or anything else in fact, except paper books. Just tell me one feature that you need for an e-reader and that isn’t available for Android 4.0… They’re all useless for e-readers.
Please do some research before posting such things lol… A scanned PDF page takes around 100kB on average. So you can have 320000 pages. And that’s only counting scanned pages. Other material takes less space.
