[Commentor] LC-285 Ian Jacobs [Comment] * The word "exploit" seems like it is being used in the French sense of "make use of". I find that in (American) English it carries a negative connotation, as when one "exploits" a security hole. * This statement is so broad that it should be dropped as a best practice note. Instead, I recommend that you create a section a the top of the document that explains what the best practices notes strive to allow people to do. For example: By following the guidance of this document, designers can: * Learn to optimize their designs for delivery to a mobile device by taking full advantage of device capabilities. * .... In short, this best practice note doesn't actually teach me anything useful. Instead, I would like to learn from the document how to do the thing you are talking about. I realize that there is an "abstract" layer and a "techniques" layer and that the abstract point is to take advantage of device capabilities, but I do not believe you have captured the right level in the above note. Instead, if you are thinking of one or two slightly more specific points, I recommend stating those instead of this very general point. [Commentor reply] yes [Working Group decision] 
* "exploit is the word used in the Device Independence authoring techniques, so we prefer being consistent with them * we think it is important to inform the reader that a good user experience on a mobile devices needs most of the time to be adapated to the device * the techniques document is the place where the reader can learn more on actual ways to learn about device capabilitiles * we have also clarified that we mean more client capabilities than just the ones required to implement the other best practices.
