Mark, my HD has 250GB, so I wasn't too concerned about partitioning it. I gave Win XP 50GB of that, but will redo it, giving the Windows partition only 32GB. At 32GB you can format the Windows partition without using NFTPS, thus making it readable and writeable under Mac OS. That should be plenty of room for Win XP, SB and maybe a couple of other games. You can probably get away with an even smaller Win partition on your MacBook. Cheers, BlackIce P.S.: Shot, my earlier link takes you to the Apple article which links to the Boot Camp download.
