O'Reilly has just released The Ruby Programming Language as a standalone iphone app! Looks like you can get your hands on it for just $5 (The cover price of the print edition is $40.) I don't have an iphone, but if you do, I'd love to hear how the book looks and works for you in that format.
At the same time, O'Reilly has dropped the ebook price for other readers from $30 to $10. Amazon's Kindle price is still $18 today. I don't know if that is going to go down or not. (Update 8/27: the kindle price is now $8.)
I'm not sure how I feel about O'Reilly using my book for their marketing experiments, but it's certainly a good deal for readers. So I ask for your help in making up for the reduced price with a massive increase in sales volume! :-)
And if I can engage in some more self-promotion: reviewers on Amazon think that this is the best book I've ever written. The 26 reviewers have all given it a 5-star rating, and the most recent review goes over the top and calls it "the best ever written programming language book". Wow. You know you want it on your iPhone!
Update: my editor says that he thinks this new ebook price is a temporary sale.
