Why do you want to wipe it though? OSX doesn't take up that much space, does it?
Good point. I wouldn't wipe it, but I would keep it minimal. At the same time, why the fuck am I using Vista so much? I like OSX better for general use.
Right now, my OSX partition is 400 gigs, and my Vista one is 100 gigs. Maybe 120ish. I forget. If I fiddled with the partitions, due to the way the beta of boot camp works, I would basically have to reformat everything, or at least that would be easiest.
I like Vista Ultimate X64 for almost everything. VistaX64 lets me use all 4gb of my ram. However, Vista is still kinda shoddy for gaming so I keep my XP partition alive.
I won't be using X64 Windows for a few years, I think. Although I bet all my hardware is supported. There are still a boatload of app and game compat issues, right?
