I have never used bootcamp to boot Windows for anything other than install/testing. Performance of XP under Fusion is awesome, and the Vista Boot Camp partition performs "adequately" (Imagine Vista on a P4 2.0GHz with 1GB RAM, and thats what its like under Fusion).
Vista performance under Boot Camp (i.e. natively booted Vista) is blazingly fast.
