Think that we can just "give every student an iPad" and presto! Education revolution? Ha. Ha ha ha. Ha ha ha ha ha. I talked to a bunch of librarians, who didn't quite laugh at my questions about e-readers and tablets and iPads in the school setting. But damn. There are a lot of obstacles: device management, distribution, vendor lock-in, DRM, and so on.
You can read my story "The Truth About Tablets" in the latest School Library Journal.
