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

To my way of thinking this means that Apple have finally admitted that Windows has a wider user base and is more functional than any Mac OS

However anybody attempting to install any version of windows on a mac computer should be aware that Apple have not and will not issue W7 compatible drivers for much of their hardware so not everything will work using Windows on a Mac
