Swathes? Maybe not a strong enough word. Do an inventory and compare it to what's in your phone. Even amongst the least technical people I know, some of them have thousands of emails, their facebook correspondances are filled with personal details, their SMS/chat history is a perfectly timestamped history of their past few years, etc. Yeah there's a few hundred, or even maybe thousands of photos in my mother's house. I'm sure there's a lot of unread magazines, too. All of that, accumulated over decades. I think it's still a safe bet there is more data in her phone would than in the combined homes of the entire neighbourhood.
