Reading the Rails beta book
I got the Rails beta book (aka Agile Web Development with Rails) and am reading the PDF on my 17" PowerBook. After hiding the dock, stretching Preview out to be full screen, hiding the drawer and the toolbar, Zooming to Fit, and setting the PDF Display to be facing, I find that I can read two pages of the book at a time! At a pretty decent font size, I might add.
It took a little bit for my order to get fulfilled, but it was worth the wait. There's over 500 pages of Ruby on Rails goodness in this book. I've been reading all the online docs and this book distills a lot of the available knowledge, while adding insights from Dave and DHH himself. It also goes through several examples, which are pretty helpful.
