Here are two videos showing Windows 7 Beta installed and running on a new MacBook Pro. The first video below is of torren version and the second one below shows off straightforward walkthrough, and head on past the break for a video of the latest beta in action on a unibody MacBook Pro. The installation was a clean install over Vista using Bootcamp, which was already running on the system. We couldn't just upgrade because the Macbook wasn't running SP1.
