I don't think anyone has actually answered the other OP's question - so here's my more specific version (and one that I think will answer that OP's question too):
Is there a software that will:
(a) Pull together all of my photos from several different devices
(b) Sort my photos by date
(c) Make it super easy to to step through them to (i) delete the ones I don't want quickly and (ii) tag the ones I do want to keep
I'm not asking about online storage or a place that can make photo books, I have those covered, I'm talking about sorting, deleting, putting dates on, tagging, etc.
