So I just got my brand new imac today. I haven't even unboxed it yet. I'm wondering about transferring my files to the Mac and how difficult it will be. I have never done anything like this before... I'm wondering if I should wait and just transfer the files to the external hard drive (that I don't have yet)...will that be harder, easier, about the same? I plan on ordering one or two very soon. Any help would be really, really appreciated.
