Some of us have important equipment interfaced to our phones (i.e. glucose meters, insulin pumps on our own bodies or that of young family members) and can't be without them. I go to 10-12 concerts a year, and I understand the sea of phones being annoying. Personally I don't take much video, if any. A few pictures, and snippets of favorite songs at best. I prefer to enjoy the moment without worrying about recording it. I hope Madonna's policy does not take hold, because that will put a screeching halt to my yearly 'concert tour'. Not to mention the lawsuits alleging discrimination this might bring about.
