Crunch time -- should I buy iMac with the new Fusion Drive OR the combined SSD + HDD? 1) I assume that Migration Assistant knows what files to put where using EITHER choice ??? 2) I am inclined toward the SSD/HDD combo because of Boot Camp/Windows 3) Same inclination because of cloning software -- SuperDuper and Carbon Copy Cloner. I absolutely do NOT know IF I am being paranoid about the Fusion Drive. However, I would welcome all definitive feedback.
