It's 11 dollars used on amazon, I'm going to opt for that one instead. I am fully with you on ebooks, reading books on screen isn't pleasurable for me at all.

edit: amazon has it for 8 dollars for the kindle( which can be read on am iphone if you're so inclined)

I bought the hard copy on amazon a few weeks ago. Best ruby books I've seen. It ranks high compared to 'best of' books for other langs as well.

Speaking of iPhone, the book is available as an iPhone app for $4.99:

They say that they worked with Lexcycle, makers of Stanza, the iPhone ebook-reader, to make this work well.

At the bottom of the page are 5 screenshots showing how the book looks on an iPhone.
