The Guardian had a interesting story entitled Are real books nearing the end of their shelf life? Some gave it a good review saying:-
Another executive from Penguin Books, a company that has issued Sony Readers to all its editors, described hers as a godsend. "I now download virtually all my submissions on to my eReader. In some cases, it means the script is never printed out. The agent emails it and I download it."
Whilst one said :-
"I can't say I enjoy it very much. Using it at home feels too much like looking at a computer screen."
With ereaders, iphones and kindles filling this area, its an interesting topic of discussion (1,2,3).
