I recently finished reading Aaron Gustafson’s Adaptive Web Design and really loved it. The book details the process behind making compelling web experiences that are adaptable to whatever device or browser the viewer happens to be using. Gustafson is a proponent of progressive enhancement, which could really just be called web standards. The idea is that by setting up the basics of the site so that they will be accessible to any browser you are free to cater the quality and features of the site to more modern browsers.
I would not hesitate to recommend this book to anyone. For anyone who wants to know what web standards exist today I would recommend the A Book Apart books for an introduction and inspiration and Adaptive Web Design for nuts and bolts.
