500N,
Good advice (as I said before) about taking one of those clear "evidence" bomb-building liquids holding bag and put everything inside before reaching security. And as I am taking a closer look on what I am carrying it is not such a big issue (two mobiles, about a pound of keys and my glasses case). Not much but it still needs to be removed on time before I reach security.
The issue remains though is asked to remove a laptop / netbook from your bag. How do you keep an eye on it if it goes to the X-Ray machine before you? And yes maybe airport security should have a responsibility to supervise ones belongings while he/she waits to walk through the metal detector.
