Obviously, I agree with you. Continuing: I really don't like the way Microsoft claims stuff they copy as "sparkling new MS technology", but that's expected. I really don't like it when Apple, the underdog, does it, even if they are playing catch-up.
I'd guess Gruber's two overexcited paragraphs were the result of his trying to reconcile the "big deal" atmosphere surrounding WWDC (e.g. inviting world media) with what little he knows about it. It goes without saying that OTA sync is not the "game changer" Apple is ready to unleash on the world. If Apple's got a real game changer (and jury is still out) they're prolly going after markets worth over $100 billion.
The smartphone was a powerful disruptive device primarily because it converged the function of many things (among others "an ipod, a phone, an internet device" as Steve repeated at the debut). Tablets also did the same thing a bit less obviously.
Currently Apple offers 4 non-mobile consumer devices: computers (mac mini and iMac), Apple TV, Air Port and Time Capsule. In addition consumers also have televisions, game consoles, DVD/Blue Ray players, and stereos.
So my theory again is that Apple is coming out with a converged device that replaces* most of the above (I don't think they will sell the actual tvs or speakers).
* It won't replace them perfectly. In fact in many cases it will be strictly worse, as in the case of cloud gaming vs console gaming. But just as the best camera is the one you have with you, the totality of having one simple device that just works will be what they are banking on.
