Breakfast briefing: Book wars erupt all over again

• The war between Amazon and Macmillan continues apace. The latest salvo? An advert in the New York Times for Atul Gawande's new book that tries to give Amazon a slap by suggesting it is "available at booksellers everywhere except Amazon." That coincided with a series of statements from authors' groups, including the US Authors' Guild , which complained that "thousands of authors and titles are affected". Oh, and the Science Fiction and Fantasy Writers of America staged their own protest . • On a similar subject, remember the Google Book Settlement - that controversial deal to let the search giant digitise millions of in-copyright titles that had so many people up in arms ? A reworked version of the agreement still isn't pleasing the US government, who filed an objection in a New York court on Thursday , saying that even though the new deal is better, it is still "a bridge too far". • And here's a good one to send you off with a smile as the weekend rolls around (or at least, it made me chuckle). Sony says it is "very interested" in making a device to compete with the iPad. IDG reports that chief financial officer Nobuyuki Oneda wants to take on the Apple gadget . "Time-wise we are a little behind the iPad, but it's a space we would like to be an active player in." Somebody might want to remind him of the Dash .
