f you've got the originals you can run every flavour of Windows including Vista
Not within your licence you can't. Vista's normal licence excludes running on virtual machines such as parallels.
I've used boot camp for about 12 months.
Its great BUT it is technically still a BETA, a very good, stable and well presented beta but a beta non the less. Thus it will invalidate your warrenty and is "unsupported" by Apple. So melt your brand new macbook and Apple will wash their hands of you.
The full release wont come till the next update to OSX later in the year.
