I got a Boox about a year ago and am very happy with it. In addition to the built in reader, I have the Kindle, B&N, Kobo and Google Play books apps on it. I only buy epubs without DRM these days, and I've de-DRMed all my purchases from all these platforms and backed them up, but if there's something I want to re-read, I find it's easier to use the apps.

I could put other apps on it, since it's essentially an Android device, but I keep it strictly for reading.

If that's true, I'm pretty much Al Capone at this point.

It practically pays for itself!

Presumably to get around FOIA requests?
