hello, I have a few questions about MacBooks that I'd like answered before I go ahead and order my first Apple. 1. I want to get a black MacBook. is it's keyboard difficult to see? 2. what is Apple's policy about dead pixels? how many can I have before I'll be allowed to return the notebook and get a new one? 3. what about a car charger for MacBooks? I couldnt find one in Apple store. 4. generally speaking, how many hours does MacBook's battery last in normal operation (web browsing, IM, word processing, etc) thanks in advance.
