Over the years Apple has made the iPhone and its iTunes software do more in the way of syncing files, applications, and other settings.

That's besides the computer used to set it up in the first place, a service Apple offers in its retail stores free of charge.
That means those users don't have any new software updates short of what their device was on when being unboxed, and if they don't have a MobileMe account--or a tie-in with some other Web sync service--their contacts, bookmarks, and calendars reside only on that device.
The sourcing on that metric is an anonymous "little birdie," so perhaps take it with a grain of salt.
