Electronic books, or ebooks, are more portable than their paper siblings, and capable of being carried in hundreds on a single electronic device. Thousands more are just a click away. It can be debated that ebooks are more robust than paper books: an ebook reader can be stolen or dropped in the bath, but the books in it are stored safely in the Cloud, waiting to be downloaded onto a new device, just like our thousand of contacts in mobile phone. Who else remembers the good old days of writing down phone numbers in a little book, to be referenced daily, flipping through the pages? Just us?
