I want to use windows xp with boot camp in OS X 10.5. Just some quick questions: 1) Does running Windows slow down the Mac partition at all? 2) Any time I turn on the computer, will I have to choose between OS X and XP? 3) How large should the XP partition be if I am only going to use it to download some applications? 4) If I later decide that I do not like boot camp, can I revert to an OS X only computer? 5) IS the setup process fairly simple? Sorry about all the questions.
