Its nothing new. Like the Zune, its clunky, 5 years too late and not innovative.
It's quite okay to prefer your Mac, but it's not okay to just make crap up. I've installed Vista on everything from an old 1.8GHz P4 to a new Core2Duo. I've yet to not find a driver for any of my printers, scanners or cameras or system devices.
And besides, can I grab some old hardware out of my closet and install OSX on it? Seems like you've set the bar a lot higher for Vista.
