I agree, there has to be a pony in this raft of rumors somewhere - is this device finally the one that actively observes it's owner's eyes (and things in the environs that it is pointed at) in anticipation of service?
That's what we need! Not an "iTablet", we need "iGoggles"/"iGlasses". Augmented reality display in your glasses, ear-buds dangling from the arms of the glasses, finger-tip recognition for manipulation (like the MIT media lab UI experiment), and proximity sensors along the arms and band of the glasses.
