You misunderstand.... Device 2 Device is still important, but the future that the NIT present is when this will be unnecessary. In the future, it _should_ be easier to stay in "sync" online than offline. Of course, not everything has WiFi or "free" internet yet, but at least some phones do.

As for business, its really not safe to carry around info on a portable device that you would not want to sync over the web. Remember, your company can sync using their own servers...

Until then, the old palm concept of sync will still be there...

P.S. One reason I don't think device 2 device information exchange will not go away is because if you meet someone on the street, and you want to exchange data, its probably easier to do it D2D, but then again, all you have to do is add each other on facebook or linkedin, and boom, all the data you want is there...
