The first thing I install when I’m setting up a Mac is Microsoft Windows XP.
I’ll likely never start up Windows again, but I’d like to have it available just in case my need becomes great in this Windoze world. Re-partitioning later could destroy your Mac OS X installation and all your precious data that you have on. Better to get it out of the way right away.
I do a similar thing if setting up a non-Mac desktop or laptop, but there I install Linux Ubuntu, and Windows.
I like to imagine Apple adding to the end of their beautiful Mac setup guide a suggestion to delay playing with your new tool and to install Windows right away. Now that would be awkward.
Or I imagine being able to order from Apple with Windows pre-installed. Makes me laugh, partially because it makes too much sense.
I believe that Apple will partner with MS someday. Yes I know it sounds like fantacy but it does make sense. After all MS would still get the license fee. My guess is that this will happen within two years.
So you actually partition your Mac yourself and not use BootCamp? Never heard that one before. I tend to lean towards Parallels Desktop for Mac myself as I have to use Windows too often. XP and Vista were Ok, but Windows 7 on Mac is quick
