You apparently think the code inside of <i>phones</i>, <i>smart card readers</i>, and <i>TV sets</i> is likely to free from security defects, and at the same time you feel qualified to argue about this?<p>You could, if you had given it 5 seconds more thought, chosen examples that were hard to falsify (even if they weren't based on any experience of your own). You might have suggested "weapons guidance" and "space shuttle life support". You wouldn't be right, except to the extent that those systems have virtually no attack surface, but at least your message board argument would be viable.
