It's actually a fairly interesting thing to do (Jury Duty), I enjoy it when I do, but I often have obligations that get in the way or make it very inconvenient. Fortunately my current job allows me to do it without issues (I still get paid, etc, etc).
I think one of the most interesting things was the way different people on the jury went about the process. Some were focused on the actual letter of the law, while others were more concerned with the spirit of the law, or it's perceived intent. Fortunately most laws don't leave a lot of room for personal perception even when you are someone who see's it as a 'spirit of the law' issue.
