Quick question. I'm out of the country and will by back in the US in mid-December. I'm planning to buy a blackbook, built to order with extra memory and a bigger hard drive. I'd like to have the notebook shipped to my folks place by the time I get there. I could order it now, but I'm afraid that it might come too quickly, thus diminishing my window for a possible return. It seems the regular macbooks are shipping within 24hrs, about how long does it take to get one built to order? That wasn't as quick as I'd thought. Thanks.
