I often think that I would be better off if I could download a book straight into my head and experience it in a second, so I didn’t have the long haul of page turning and carrying it around. Also I’d get few a fair few more books.
When I thought about it longer I decided that half the point of reading a book is to deliberate over it and spend time with it, get to know characters, think about the story while you’re away from the book. You’d miss those things if you had an instant book download.
Another one of my “good” ideas which I quickly see the downside of.
I think that instant book downloading will be after ebooks but before facebook becomes a human organ that we can’t live with out.
