Paper books will survive simply because they don't require a technological means of consumption. I suspect that we will become much more selective about what we publish on paper. Convenience will be a large factor: ebooks will be easier to obtain and provide far fewer hurdles for those who maintain a personal library.

Advocates of ebooks seem to overlook many of the issues with ebooks. While it is true that electronic resources are easier to replicate and can be preserved indefinitely, it requires far more intervention. The media that ebooks are stored on is usually much more frail than the media print books are stored on, necessitating backups. The standards used to encode ebooks are also far more dynamic. That is especially true for DRM, but also holds true for the underlying file formats. This isn't impossible to overcome, but does require knowledge and planning on the part of the user.
