Reader: It does not support DRM’d files. If you don’t want to figure out how to work around this issue, it’s not for you.
Export: There’s an app you can use to sync your documents automatically. Export to PDF is entirely supported.
Internet: No, it does not have a browser.
RSS: No, it doesn’t have a feed reader. You could set something up to export feed content and then import it into your device.

Migration complete. Thanks everyone!

TLDR; No
