Hi. I have the new MBP. I heard its possible to have both Windows XP and Mac OS running at the same time. I have some questions concerning this: -Does this slow down your macbook pro? -Will anything I save on Windows XP be accessible on Mac OS? (i.e. if I am chatting on Yahoo on Windows XP and someone sends me a photo, is it accessible on both XP and Mac OS, or just XP)? -If I want to transfer something from my pen drive to the notebook, and only want it to appear on Windows XP and not in Mac OS, is that possible? -Does the multi-touch functions on the trackpad still work if using Windows XP? -How do I go about getting XP and installing/running it on my MBP simultaneously with Mac OS? (and is XP like a program I launch once I normally log into my Mac OS that I can open and close as I please)? Thanks for your help!
