Sorry for this very ignorant question. I've seen numerous threads in the past regarding the different software options for running Windows on a Mac. I've even read them having considered it in the past and wanting to know my options but never went through with it. Now I actually do need to do this and with the ever changing software options (ex: Parallels 5 just came out) I wanted to know the current available choices and which is best. In the past I've seen Fusion as being faster and better than Parallels. Why then do so many people choose Parallels? And what's this Boot Camp option? I am running Snow Leopard, isn't this included? I'm obviously new to this, my sincerest apologies for posting such a thread but I haven't been able to find good info. Also, should I stay with Windows XP or use Windows 7 since it's the latest release?
