Security is such nonsense now. I don't fly THAT often, but I've got a system in place. I've basically resigned myself to getting dressed on the other side of security. Before I even get in the line, my shoes are untied, belt is in my bag along with cell phone, keys, etc, laptop is out (out of its case, not its sleeve) as is my 1qt ziplock. I proceed through security, go to the first set of chairs available, then get dressed =P.
