I have done some JS/DOM scripting, but limited in terms of what is probably needed for canvas. I agree with the having something handy nature of a book, plus I find it difficult to read too much on screen, a paper copy is more amenable to me.

And although interested in CSS3 and canvas, I'm also interested in finding out how HTML5 differs from HTML4 (semantic and sloppy tags aside).

Thanks Peter, but I'm one of those weirdoes that likes a book next to me while I work on the computer. Strange, no?

But you raise a good point about bandwagon jumpers. If Danny Goodman had revised his Dynamic HTML reference since 2006 to include HTML5 I'd snap it up in a heartbeat. The first two editions are indispensable to me. In fact, I might just get the third edition because it covers Ajax and I know little about it.
