It's a trade-off. I love the convenience of ebooks, but not owning my books is just categorically unacceptable to me. I want my daughter and anyone else coming after me to have free access to them, not to have to jump through Amazon's hoops (if such hoops even exist) for access.

I have a Kobo that I use to read the non-DRM ebooks I'm able to acquire. One such source is downloads from the Kobo store, when publishers make the non-DRM file available.
