More than a little. I'm beating my favorite patent drum again, but one of Apple's alleged "inventions" (that amazingly survived first-round review at the ITC) is this:

http://www.google.com (i.e. recognizing things like URLs in free-form text and turning them into clickable actions).

Prior art for this includes such obscure pieces of software as Netscape Navigator 2 ("live" URLs in mail and newsgroup messages), released months before Apple filed for this patent.
