I've read many threads about doing a fresh install of SL as soon as the iMac arrives. I haven't really seen a final decision on this. I've read about the boot time being much faster after a fresh install, but also that there are other ways to do it without having to completely reinstalling SL. Should I: -Do a fresh install? -Leave it as is? -Change certain options to get the same effect? -Other option you post about?
