Tablets are going to expose all sorts of new ways of interacting with hypertext on the client side. Supporting html5 is nice for authors, but the real revolution comes when readers can compare multiple hypertext documents, naturally browse through interlinked documents, make annotations, etc. These things have been tried and failed on other form factors, but I think they might succeed on a device like this, Courier or the iPad where the new form-factor requires new interaction models anyway.<p>This device doesn't look perfect, but they're exploring the most interesting aspect of the tablet problem.
