Posting from a mackbook pro right now. I used boot camp to load windows XP (needed it for some apps at work that require windows). So I have the best of both worlds. Just chose my OS at start up. The Mac OS is not error free. It's supposed to be so great for video editing. As soon as I connect my Panasonic HD camcorder to it the OS locks up. One other weird thing is I get 4 hrs of battery life using the mac os. I only get about an hour using XP. I still can't figure that one out.The fit an finish on this laptop is far superior to any Dell, Toshiba, HP, etc.
