Fedora Linux has been available in print format for a week and a half, and has sold several thousand copies (many of them just to fill the pipeline, I'm sure). It's widely available through online sellers, but is not in stock at many brick-and-mortar stores yet. Safari Online access to the book and a PDF format download are also available.
And, thanks to Google Alerts, I see that the first review has now been posted. I can't tell you how nerve-wracking it has been, waiting to see what people think! (If you have the book ... there are no reviews or ratings on the online booksellers' sites yet ... tell the world what you think!).
I believe that it is a great book. I have ordered it about 10 days before and it is not shipped yet. I think book is getting popular, that's why it is hard to get it now. But anyway, I will post my comment as well as soon as I'll receive my, I mean, your book:)))
