Hello everybody! I'm going to the USA in december and I'm planning to buy an iBook 12" for me. But before that, I want some help from you. What are the essential accessories I can't forget to buy? Does the iWork worth $79? It's my first time at the USA, and I want to know too if I have to pay extra taxes to bring the computer with me to Brazil. Somebody told me that the limit of products that you can buy there is $500, probably in order to prevent the tourists of buying cheap equipment and selling it in their countries. But the iBook would stay with me. Anybody knows how does this work? Thank you very much!
