Bad Pink Tink - I don't think that we are getting in a fluff about it. We are all just trying to understand what is required for something that is new. And it is an annoyance, in the "gosh, here is yet another thing that I have to do" type of way. And my oldest DD is trying to plan a trip to London to visit a friend who is studying there and she was annoyed at the cost of this (she is very frugal with her own money, just not mine).
And likely a lot of Americans were not aware that foreign visitors to the US have been doing something similar for years. That isn't surprising - it didn't apply to us and we go through different passport lines when coming into the US and we wouldn't be looking at the US entry requirements for tourists. (And a lot of Americans have never traveled out of the US, just like a lot of Europeans have never left Europe, or even their own country.)
