Anyone have any thoughts (or experience) for how well Vista (and/or XP) run on these? I guess the issues are that they ship with an Nvidia "chipset" (which isn't really a "set" since it's one chip, but you know what I mean...) and the touchpad might be an issue if Apple didn't write good Windows drivers for it (though they seemed to write excellent drivers for their previous MBP, so I bet they did for this too).
