What I really need is something that allows both my laptop and my wife's laptop to view and edit the photos. Not even simultaneously. Just from two different machines and two different accounts. Right now we store the photos on a NAS Picasa to view and edit them. (Picasa hates network drives, but symlink magic fixes that.) I don't really like Picasa (It insists on G+ too much, and the UI doesn't integrate well with MacOSX, specifically Finder.), but it works better than iPhoto for large collections. Unless I'm mistaken, this looks like the standard Apple approach where its tied to a single iCloud account. Is family photo sharing/editing really that difficult? We can't be the only ones that want that right? Also 1 TB isn't enough space. We have 14 years of photos we'd have to upload. That's a lot, and these price points are just too expensive.
