bears "include SP 3"!? What does this "include" mean? Does it mean that SP 3 is integrated into the OS or it is optional? My question is "Should I buy this Windows XP or not? Does it give me the option to ignore Service Pack 3 and just install SP 2?" I am asking his question since Mac warns that SP 3 must not be installed via Boot Camp. On the other hand, if I unseal Windows CD to try it, I cannot return it! Please help if you can. Thanks.
