&gt; that is exactly how most families operate.<p>Do you have non-anecdotal evidence for that? Among my own friends and family, there are some images that only exist on one device or account, but most of the stuff likely to draw interest ends up somewhere else (a shared Dropbox account, e-mail attachments, on Facebook, copied onto some form of external storage).<p>There are likely some demographic groups that are more likely to behave one way than the other, and that could perhaps account for our differing experiences.<p>On second though, it <i>is</i> the easiest way to use the account (each person having an account on each device). I wonder what percentage of people that would benefit from it actually use the Family Sharing option?
