Will be interested to hear your review after using it. Especially on 3 points, if you have time:
1. Performance on more demanding tasks besides reading. Like: running video, loading a complex page (like CNN.com) in the browser, etc.
2. Ability to run the Google Play store and standard apps that you like, for reading or other things. Email, video, whatever.
3. Battery life.

I will also be interested over time to see if folks have any issues with these new e-ink Androids that are running v6. That seems to me like a security breach waiting to happen, as Google stopped patching that version long, long ago. But as someone said in another thread, maybe there is less risk with these e-ink androids for people who are using them ONLY as an ereader. That may well be true, particularly if you don't install any apps that have to do with shopping, payment, authentication, or email. But then...why bother getting an ANDROID e-reader, if you're not going to use any of those Android apps besides the reader ones?
