Apple recently released 1.2 beta of its bootcamp software, one of the key new feature is support for Vista. So I couldn't resist and after shuffling some files to free some space, I installed Vista on my Macbook Pro C2D. Installation was very simple, basically install Vista as per normal, then install the Mac drivers by inserting a Mac drivers CD that you create using the bootcamp assistant.
Vista reported I have a 4.7 Windows Experience Index. So far the laptop is working ok under Vista, some features such as automatic screen brightness and keyboard illumination doesn't work. One complaint is that when booted into Vista, the hardware makes a high pitch noise.
