My own personal experience is that iOS 8's feature set is muted until Yosemite comes out. Once people with recent enough devices are able to enjoy Continuity, Handoff, and fully experience iCloud Drive, then adoption will (I predict) increase; and I believe the "not much difference" statements (which are arguably currently correct) will subside. I believe Apple could have done well to coordinate a simultaneous launch for Yosemite and iOS 8.
