Hello ! I have a question regarding the new MacBook Air 13". In February I'm going to USA NY for a two week vacation (I am from EU). I would like to buy the new MacBook Air while I'm in NY, because I can save 600$ If I buy it in USA rather then in my country. However, I would like to buy not the basic version but the one with 4Gb RAM- 1.86GHz Intel Core 2 Duo 4GB 1066MHz DDR3 SDRAM 128GB Flash Storage The question is do I need to order before I go to USA, or I can just walk in any Apple store in NY and they will have this specific version of MacBook Air ? Another question is regarding warranty. Should I buy it or not ? For example when I bought my Canon 40d, I also spend additional 200$ for internation warranty. I never used it and now it is over. Oh, one more thing. I have heard that newegg.com is one of the best store for computer parts. However as far as I understand they don't have an actual store, they sell items online and then they deliver them by mail. Does that means that I can't buy computer items from them as I'm staying in a hotel ? Thank You.
