Btw. the Java User Group meetings are located in a book store in Hamburg - with a considerable amount of Java books. They told me - that the Java ONE top selling books are all available and discounted. ...the Java area is significantly bigger, comparing it to the .NET (at least yesterday - during the JUG-meeting :-)).
The best of all - I got a PI-mug afterwards - but the JUG-leader didn't knew the PI Movie (it's really great hacker movie with the same name)... I would expect to have at least one DVD in the shop :-).
