Comments on The Pocket Idiot's Guide to Hold'em?

[MRBAA]

The book has enjoyed excellent sales, gone through many printings and we're now considering updating. If anyone has read it, I'd be interested in comments on what could be improved/added. It's a beginner book, but we've tried to include some fairly advanced strategy information in a simple form. There's a look inside on Amazon which gives a few introductory pages, which are not about strategy, as well as the index.
