I too, was nailed by these "security" questions. I am livid with Apple. They insituted this without warning and I find the questions too intrusive. I would not put it past Apple to share the answers such as the type of our first car or year of our birth for marketing purposes.
I have had an Apple ID since the inception of the Dot Mac service. It has worked very well for me and I see no reason for Apple to unilaterally decide this matter for me. I believe they do not want to admit that there are vulnerabilities in the security protocols for iTunes, or their system software.
I have been using Apple products for 25 years and until yesterday, I was fairly happy. I have seen the light. Apple does not value me as a customer. I am returning my new iPad HD and Apple TV. I am no longer going to waste money with the iTunes or app store. Why? Very simple. What will be their next bar to achieve if you want to keep using your content. I can see them requiring a future software upgrade to continue to use the content that we have purchased. I can see them changing the game again with another enhancement. Suppose they requested the password to your online banking. Would we need to give that to them as well?
There comes a point where security becomes a game of the paranoid. Yes, they are going to pull you name out of thin air. Out of the 8 billion people on earth, you are it. Come on. I can understand some degree of security, but the questions Apple implemented are over the top. I will not answer the questions so my course is charted. I am no longer able to buy their stuff or use their stuff in a meaningful way. Will I miss using Apple products? Yes. The hardware was great and the software worked fairly well for the most part.
I will not submit to Apple's intrusiveness. There will be some who will write in here that I am not being reasonable. Maybe, maybe not. Apple is getting to be too intrusive and they are also ignoring the customers.
Good luck to all you who continue to use the service. By tomorrow night there will be a slightly used iPad and Apple TV in great shape sitting in a Best Buy near you that will be marked down.
A big thank you to Apple for helping me to see the light.
