I think many of us feel the same way.
Before Photos.app there weren't tools that allowed people to have their entire library almost everywhere.<p>Yes, you could sync all the library to flickr, and it would work like a charm (btw they updated the mac uploader, worth a try), but you would still lose all the benefit of having them in your computer.<p>Now that's possible, and you can also have less disk space and "reclaim" the real photo whenever you need it.<p>That's a big improvement.
