After some reading about Photos, I'm beginning to see one big reason they are pushing this is for the ability to charge monthly fee for storing photos online... Why can't they incorporate 'Iphoto Library Manager' and give user the ability to divide iphoto libraries into smaller chunks and let users easily store them on external Hds?
