Jason Snell, writing for Macworld:
Family Sharing feels very much like a version 1.0, a first crack at the idea that people with their own Apple IDs also have intermingled real lives that should probably be intermingled digitally. Nearly two years after the release of iOS 8, however, not a whole lot has changed in the realm of family sharing. And it’s got some glaring deficiencies that really need to be addressed.
Jason runs down a few features that Apple could add to improve Family Sharing. And his list includes the one feature I want most — family photo libraries. It doesn’t make any sense that my wife and I have to maintain two separate libraries. It makes ordering prints, creating photo albums, and working on other creative projects significantly more difficult. I hope Apple fixes this soon.
