Well clearly from phone to everything else is very rapid.

But from photos app on computer (desktop), you add photos in from a hardrive, they just don't move or get synced at all...

My point is sometimes I want to get photos from storage (hardrive) onto the iphone, and your method of using photos app on desktop is great (as opposed to having to plug in my iphone and do an upload), but it needs this push of sharing, creating an album to get icloud's attention.
