I’m writing an article about their usage, and would love to see (and perhaps feature) some sites that use a dedicated icon for either or both. I read about the Apple touch icons in an article on Six Revisions by our guy Alex Dawson. Opera 11 uses a client-customizable icon if the designer/developer wants to use one.
SitePoint uses one (or something similar), as does [URL=“http://www.apple.com/”]Apple and [URL=“http://www.nbc.com/”]NBC.com. [URL=“http://www.iraqtimeline.com/maxdesign/”]So do I, as of this afternoon. Most sites don’t, even Apple’s iPhone and iPad sites.
Sing out if you’ve implemented one in one of your designs. Warning: you may get quoted and/or linked. Thanks!
