I am planning on switching to an iBook soon, hopefully within the next month, and I have 2 questions. I know this might sound stupid, but is there an equivalant (sp?)in Mac OS X to "NTLDR" in Windows XP? Some how I always lose this file and must reinstall XP. My last question is right now I have a wireless keyboard that does not have Mac Commands. Will I be able to use the "control" and "alt" key as what it is in Mac OS X?
