I love the convenience of Kindle e-books -- readable on my phone, tablet, and Kindle device -- but I miss the ownership benefits of physical books. It's nice to be able to freely lend, sell, or donate books. I think that laws need to evolve to guarantee that e-book owners have the same options.
To be fair, in my home (developing) country, people mostly pirate their digital books anyway. Hardware on which to read them properly would be more appreciated.
Our government recently gave e-readers preloaded with some books in the public domain and others donated by local writers to children in some schools to encourage reading.
