(I know there was already a thread on the movie, this isn't about the movie.)
For anyone who saw/will see/doesn't want to bother seeing the movie but is too cheap or lazy to go out and get a copy of the book, I have a solution: The Hitchhiker's Guide, in its entirety, in Ebook format. Enjoy. You know, if you like reading. If you're into the "information in the form of written words" thing. I hear it's becoming less popular lately. Oh well. Here it is anyway.
