Some interesting picks this year. Google Maps API 2005 under the Database Engines and Data Tools section? Thats surprising, but I bet it will win. (since most of the other tools are just new releases of existing databases)
Cool to see the Brad Adams Design Guidelines book in the Technical list, also good to see the Rails book which will almost surely win. Rails makes another appearance down in the Web Development Tools section where it will probably win as well. The rest of the categories don’t have too many surprises.
