I'm up for a challenge: 10 wonderful reasons to embrace digital books.

1: Less materialism

Embracing any digital formats will either consciously or subconsciously change the way we think about, show and share material possessions. Many people know about 'less is more' and often want a minimal lifestyle, but can't actually introduce the changes required to do so. Digital print, whilst initially is a shock to the system, gradually starts this change to an ultimately 'lighter' way of living. Those people that value, showing off their reading achievements by displaying a vast library of books, will still want this understandably, and this 'need' in a digital format, will push forword application development which takes the library from an e-reader to a tv/projector/display, pulling book covers and spine imagery from online locations and presents them accordingly to reflect a traditional bookshelf of bound manuscripts.

2: Portability
