Off the top of my head, the Visa Waiver Form asks...
Name, sex, DOB, nationality, country of residence, passport number, flight no, address where you are staying in the US, then on the back there is a whole host of boxes you have to tick if you are a convict, wanted for terrorism, war crimes, etc. which I must admit seems nuts...I mean, if you are...as if you are going to answer YES
The 2nd form is the customs form. Name, etc, plus asking if you are bringing anything in with you to declare or not.
A bit of a pain, but still....much better than having to apply for a visa to enter the country like you used to!
