Windows 7 and Apple BootCamp.

So far, Apple does not ‘officially’ support Windows 7 on BootCamp.  Their site released a statement on October 22, 2009 and it has not been updated.  Apple states:

Apple will support Microsoft Windows 7 (Home Premium, Professional, and Ultimate) with Boot Camp in Mac OS X Snow Leopard before the end of the year. This support will require a software update to Boot Camp.

With that being said, most Mac users are able to install Windows 7 on BootCamp without any issues.  Here are a few links to forums that discuss this and installation help.
