A Web 2.0 book

Susan Kelley spotted Dive Into® Web 2.0, a book by Deitel & Associates. The book covers many of the same topics we do, and there is also an extensive online resource center -- you should check it out.

Like other publishers we have discussed, Deitel offers electronic and print versions of the book. You can read the HTML version free online or order a PDF file or a hard copy from on-demand publisher lulu.com. It will be interesting to see if they are able to keep the HTML and PDF versions synchronized.

This 81 page book is $19.95 in hard copy, $9.95 as a PDF file and the HTML version is free. Assuming you want a book, which version would you select at those prices? Would you like to read it on a portable device?
