In a bold move today, Apple has released a public beta of Boot Camp, a piece of technology that will be integrated with Leopard that is just for Intel Macs. Why is it so bold? Boot Camp allows you to dual boot Windows XP and OS X on any Intel Mac. The software even includes Mac specific drivers for networking, graphics, audio, Airport wireless, and bluetooth (amongst other things).
You can download the public beta right now (it checks in at 83MB).
