I just got aperture in the mail today, and I've spent all day watching the tutorials at apple.com and playing with the software. My question is, is there any reason to use iPhoto as a media manager? i.e. keep images stored in the iPhoto library. I already imported my iphoto library "to the aperture library", would it be safe to delete my iPhoto library? id hate to delete it and then i lose off of my masters. id prefer to use aperture exclusively unless there is a very good reason to use both. thanks in advance.
