Oh, come on, *Sun's own downloadable documentation* doesn't count.
Doorstops with a big JAVA in a saturated primary color sitting on
bookstore shelves, and "ebooks" that cost twice as much and are full of
evil DRM, on the other hand ...

Mind you, we ARE entering a new era, in which the Almighty Thud* has
taken on a whole new meaning -- it's the sound you hear three hours
after clicking "Download SDK API documentation" links for large Java
class libraries, esp. the core JDK ones themselves. :) (It's also the
sound you hear a little later, seeing the Disk Full error with the
progress bar at 90%, when you bang your head repeatedly against the case
containing the 250GB Maxtor drive you just clogged with it all.)
