From a ZDNet article:
The new offering would allow people to sign in and purchase immediate, browser-based access to books, Google said on its site. Purchasers would not, however, be allowed to save a copy of the book to their computer or to otherwise copy pages from the book.
Hmmmm. Web-based access only? An interesting idea. For reading fiction, I think I still prefer the physicality of holding a book. Reference material might be different though. That’s something which I might want to access from anywhere. Anywhere with web access, that is. It’ll be interesting to see how this works out. I imagine there are plenty of people who like this purchasing model.
