The Google Books blog has an explanation of how they attempt to answer a difficult but commonly asked question: how many different books are there? Various cataloging systems are fraught with duplicates and input errors, and only encompass a fraction of the total distinct titles. They also vary widely by region, and they haven't been around nearly as long as humanity has been writing books. "When evaluating record similarity, not all attributes are created equal. For example, when two records contain the same ISBN this is a very strong (but not absolute) signal that they describe the same book, but if they contain different ISBNs, then they definitely describe different books. We trust OCLC and LCCN number similarity slightly less, both because of the inconsistencies noted above and because these numbers do not have checksums, so catalogers have a tendency to mistype them." After refining the data as much as they could, they estimated there are 129,864,880 different books in the world.

Even just a game like WoW might be enough to make it happen, and Gaikai's Dave Perry posted a picture of doing just that on an iPad. So is it the future or not? Could somebody make a tablet with nothing more than a screen, battery, network port, and video decoder, and have it be a good gaming platform? Will it change the mobile, PC, console, and TV world as we know it? Lots of questions, lots of skepticism, lots of players and money being invested — but one thing is for sure: it will be very interesting to see how this evolves."
