I would argue niether. The Rabbit device still needs to be coupled to a smartphone and would therefore be a lot better if it took the form of a watch. As soon as Apple finally get some extra smarts in Siri and it ca last 18 hours with 4G turned on the Smartwatch will likely supplant the phone as the default communication paradigm as it has all te strengths and none of the addiction.

VR Goggles have industry written all over them, indeed this is where the Apple Vision will find its first success.
