Not to put too fine a point on it, but you're wrong (and NovemberWhiskey is right). We've had syncing for ages, sure - but we've never been able to instantly pick up exactly where we left off on a different device, until now. That's what Handoff is, according to Apple. Obviously we need a way to access the feature using the GUI (lock screen and multitasking interface icons), but the feature itself is very clearly described by Apple on their site as real-time syncing of apps between iOS and Macs.
Thanks. Not sure how that guy can disagree so vehemently in the face of the Keynote (which he claims to have watched) which describes Handoff (AND demonstrates it) precisely as we have described it.
Sometimes the internet is mysterious.
