I use my iMac at home as a hub. My contacts, calendars, and itunes stuff is of course in the cloud, and all my iDevices are connected to it. But all non iTunes media, and my photos outside of what I sync up in photo stream, are still synced of my iMac.
Then there are personal documents and such, which get synced to everything via dropbox. Including a subset of photos I upload from my phone, and all my dSLR photos.
