I fly on average at least twice a year. And I have done so since before 9/11. They really have gone too far. It really isn't necessary for the small amount that they likely prevent with the new security measures.
And yes, it is very annoying to fly when everyone has to stand in line and is treated like we're all terrorists because they can't figure out how that we are already relatively as safe as we are going to get. In fact, we were almost as safe as we were going to get before 9/11. The biggest failure in our security prior to 9/11 was that everyone was taught that if terrorists take over your plane, you do nothing to provoke them and you will get out alive, no matter what they are using to hold the plane with.
I don't like losing freedom for security. Terrorist attacks are tragic but lost freedom is worse.
