The latest release of Bootcamp provides all the correct drivers so that your
Windows Drive can also use all the other features of your machine optimized for that specific machine.
In reality, you don't really NEED a Windows machine, just a Windows Drive.
Your Mac is the Controller.
Windows is FINE if....... you turn your Windows system into a dedicated OFFLINE or secure network only workstation/gaming rig.
No internet surfing, e-mail, chat, google nothing.
You do all that on your personal Mac OS X drive.
If you have a nosy IT policy at work, you can now set up your Windows Volume as a strictly squeeky clean work machine in full compliance with company policies.
They can scan your company XP drive till the cows come home and they'll
never have a clue about any personal stuff on your OS X drive.
Their server will see your XP drive as just another windows machine.
Even better if your XP drive Volume is on an external hard drive.
